TPM-MIB

AppLocalIndexA locally arbitrary unique identifier associated with an application or application verb. All objects of type AppLocalIndex are assigned by the agent out of a common number space. In other words, AppLocalIndex values assigned to entries in one table must not overlap with AppLocalIndex values assigned to entries in another table. Further, every protocolDirLocalIndex value registered by the agent automatically assigns the same value out of the AppLocalIndex number space. For example, if the protocolDirLocalIndex values { 1, 3, 5, 7 } have been assigned, and the apmHttpFilterAppLocalIndex values { 6, 8, 9 } have been assigned: - Assignment of new AppLocalIndex values must not use the values { 1, 3, 5, 6, 7, 8, 9 }. - AppLocalIndex values { 1, 3, 5, 7 } are automatically assigned and are associated with the identical value of protocolDirLocalIndex. In particular, an entry in the apmAppDirTable indexed by a value provides further information about a protocol indexed by the same value in the protocolDirTable of RMON2. The value for each supported application must remain constant at least from one re-initialization of the entity's network management system to the next re-initialization, except that if an application is deleted and re-created, it must be re-created with a new value that has not been used since the last re-initialization. The specific value is meaningful only within a given SNMP entity. An AppLocalIndex value must not be re-used until the next agent restart. (1..2147483647) · Unsigned32

An index used to uniquely identify the application with which the entries in the tpmTransMetricDir table are associated.

TpmTransactionMetricIndexAn index used to identify an entry in the tpmTransMetricDir table uniquely. Each such entry defines the protocol transaction and metric instance to be monitored for a specific application. (1..65535) · Unsigned32 · hint d

An index used to uniquely identify an entry in the tpmTransMetricDir table. Each such entry defines protocol transaction and metric instance to be monitored for a specific application.

Unsigned32 (1..2147483647)

The protocolDirLocalIndex of the particular transaction to be analyzed when computing and generating the selected metric for a specific application.

Unsigned32 (1..2147483647)

The tpmMetricDefinitionID of the particular metric to be generated.

INTEGER1 = notSupported2 = supportedOff3 = supportedOn · Integer32

This object describes and configures the probe's support for this performance metric in relationship to the specified transaction and application. The agent creates entries in this table for all metric and transaction combinations that it can generate. Because the probe will only populate this table with supported entries, and the table cannot have entries added, the notSupported(1) setting is only used to signify that other configuration parameters are causing the agent currently not to support the generation and collection of this metric for the specified protocol and application. Also, the status of this object will not change to notSupported(1) due to a change to supportedOff(2) in the tpmMetricDir table. If the value of this object is notSupported(1), the probe will not perform computations for this performance metric and transaction combination and will not allow this object to be changed to any other value. If the value of this object is supportedOn(3), the probe supports computations for this performance metric and protocol and is configured to perform the computations for this performance metric and protocol combination for the application for all interfaces. If the value of this object is supportedOff(2), the probe supports computations for this performance metric for the specified protocol, but is configured not to perform the computations for this performance metric and protocol for the application for any interfaces. Whenever this value changes from supportedOn(3) to supportedOff(2), the probe shall cause the deletion of all entries in the tpmReportGroup tables, for all appropriate studies configured in the tpmAggrReportCntrlTable. The value of this object must persist across reboots.

TpmMetricDefIDAn index that identifies through reference to a specific performance metrics. The metrics are referenced through their type (connect, delay, loss, etc.), their directional characteristics (one-way, round trip, etc.), their name, and their reference to a documented definition. (1..2147483647) · Unsigned32 · hint d

The index for this entry. This object identifies the particular metric in this MIB module.

INTEGER1 = other2 = connectMetric3 = delayMetric4 = lossMetric · Integer32

The basic type of metric indicated by this entry. The value 'other(1)' indicates that this metric cannot be characterized by any of the remaining enumerations specified for this object. The value 'connectMetric(2)' indicates that this metric measures connectivity characteristics. The value 'delayMetric(3)' indicates that this metric measures delay characteristics. The value 'lossMetric(4)' indicates that this metric measures loss characteristics.

INTEGER1 = oneWay2 = twoWay3 = multiWay · Integer32

The directional characteristics of the this metric. The value 'oneWay(1)' indicates that this metric is measured with some sort of unidirectional test. The value 'twoWay(2)' indicates that this metric is measured with some sort of bidirectional test. The value 'multiWay(3)' indicates that this metric is measured with some combination of unidirectional and/or bidirectional tests.

SnmpAdminStringAn octet string containing administrative information, preferably in human-readable form. To facilitate internationalization, this information is represented using the ISO/IEC IS 10646-1 character set, encoded as an octet string using the UTF-8 transformation format described in [RFC2279]. Since additional code points are added by amendments to the 10646 standard from time to time, implementations must be prepared to encounter any code point from 0x00000000 to 0x7fffffff. Byte sequences that do not correspond to the valid UTF-8 encoding of a code point or are outside this range are prohibited. The use of control codes should be avoided. When it is necessary to represent a newline, the control code sequence CR LF should be used. The use of leading or trailing white space should be avoided. For code points not directly supported by user interface hardware or software, an alternative means of entry and display, such as hexadecimal, may be provided. For information encoded in 7-bit US-ASCII, the UTF-8 encoding is identical to the US-ASCII encoding. UTF-8 may require multiple bytes to represent a single character / code point; thus the length of this object in octets may be different from the number of characters encoded. Similarly, size constraints refer to the number of encoded octets, not the number of characters represented by an encoding. Note that when this TC is used for an object that is used or envisioned to be used as an index, then a SIZE restriction MUST be specified so that the number of sub-identifiers for any object instance does not exceed the limit of 128, as defined by [RFC3416]. Note that the size of an SnmpAdminString object is measured in octets, not characters. SIZE (0..255) · OCTET STRING · hint 255t

The textual name of this metric. For example, if this tpmMetricDefEntry identified the IPPM metric for round trip delay, then this object should contain the value, e.g., 'Type-P-Round-Trip-Delay'.

This object contains a reference to the document that defines this metric. If this document is available online via electronic download, then a de-referencable URL should be specified in this object. The implementation must support an HTTP URL type and may support additional types of de-referencable URLs such as an FTP type. For example, if this tpmMetricDefName identified the IPPM metric 'Type-P-Round-Trip-Delay', then this object should contain the value, e.g., 'http://www.ietf.org/rfc/rfc2681.txt'.

OBJECT IDENTIFIER

This object contains a reference to the Object ID in a metrics registration MIB being developed in the IPPM WG at the IETF; e.g., the IPPM-REGISTRY-MIB [RFC4148], which defines the metric. In the event that this metric has no corresponding object identifier (OID) or until the IPPM-REGISTRY-MIB is defined, then the value should be set to 0.0 for none.

Unsigned32 (1..65535)

An index that uniquely identifies an entry in the tpmAggrReportCntrlTable. Each such entry defines a unique report whose results are placed in the tpmAggrReportTable on behalf of this tpmAggrReportCntrlEntry.

Unsigned32 (0..65535)

This index associates this TpmAggrReportCntrlEntry directly with an existing ApmReportControlEntry. This link is used to synchronize reports in the associated tpmAggrReportTable. A value of 0 (zero) enables an independent control table that will report entries to tpmAggrReportTable based only on the other objects in this table. A non-zero value indicates that this row is defined through the APM-MIB. In this case, all row objects are set to their corresponding values in the APM-MIB. In the event that a SET is issued to a row object, while the value of the tpmAggrReportCntrlApmCntrlIndex is non-zero, the agent MUST respond as if the object of the SET command had MAX-ACCESS of read-only. This object may not be modified if the associated tpmAggrReportCntrlStatus object is equal to active(1).

DataSourceOrZeroIdentifies the source of the data that the associated function is configured to analyze. This source can be any interface on this device. In order to identify a particular interface, this object shall identify the instance of the ifIndex object, defined in [4], for the desired interface. For example, if an entry were to receive data from interface #1, this object would be set to ifIndex.1. If the source of the data isn't an interface or cannot be localized to an interface, this object would be set to 0.0Reference: The DataSource textual convention is defined in RFC 2021 [5]. · OBJECT IDENTIFIER

The source of the data for TPM Reports generated on behalf of this tpmAggrReportCntrlEntry. If the measurement is being performed by a probe, this should be set to the interface or port where data was received for analysis. If the measurement isn't being performed by a probe this should be set to the primary interface over which the measurement is being performed. If the measurement isn't being performed by a probe and there is no primary interface, or if this information isn't known, this object should be set to 0.0. If the tpmAggrReportCntrlApmCntrlIndex is non-zero, then this object is set to the corresponding apmReportControlTable object in the APM-MIB [RFC3729]. This object may not be modified if the associated tpmAggrReportCntrlStatus object is equal to active(1).

TransactionAggregationType1 = flows2 = clients3 = servers4 = applicationsSpecifies one of 4 different techniques for aggregating transactions. The metrics for a single transaction are the responsiveness of the transaction and whether the transaction succeeded (a boolean). When such metrics are aggregated in this MIB Module, these metrics are replaced by averages and distributions of responsiveness and availability. The metrics describing aggregates are constant no matter which type of aggregation is being performed. These metrics may be found in the apmReportTable. The flows(1) aggregation is the simplest. All transactions that share common application/server/client 3-tuples are aggregated together, resulting in a set of metrics for all such unique 3-tuples. The clients(2) aggregation results in somewhat more aggregation (i.e., fewer resulting records). All transactions that share common application/client tuples are aggregated together, resulting in a set of metrics for all such unique tuples. The servers(3) aggregation usually results in still more aggregation (i.e., fewer resulting records). All transactions that share common application/server tuples are aggregated together, resulting in a set of metrics for all such unique tuples. The applications(4) aggregation results in the most aggregation (i.e., the fewest resulting records). All transactions that share a common application are aggregated together, resulting in a set of metrics for all such unique applications. Note that it is not meaningful to aggregate applications, as different applications have widely varying characteristics. As a result, this set of aggregations is complete. · Integer32

The type of aggregation being performed for this set of reports. If the tpmAggrReportCntrlApmCntrlIndex is non-zero, then this object should be set by the agent to the value of the apmReportControlAggregationType object. This object may not be modified if the associated tpmAggrReportCntrlStatus object is equal to active(1).

Unsigned32 · Seconds

The interval in seconds over which data is accumulated before being aggregated into a report in the tpmAggrReportTable. All reports with the same tpmAggrReportCntrlIndex will be based on the same interval. If the tpmAggrReportCntrlApmCntrlIndex is non-zero, then this object should be set by the agent to the value of the apmReportControlControlInterval object. This object may not be modified if the associated tpmReportAggregateCntrlStatus object is equal to active(1).

Unsigned32

The maximum number of Client and Server combination entries requested for this report. If the tpmAggrReportCntrlApmCntrlIndex is non-zero, then this object should be set by the agent to the value of the apmReportControlRequestedSize object. When this object is created or modified, the probe should set tpmReportCntrlGrantedSize as closely to this object as is possible for the particular probe implementation and available resources. It is important to note that this value is the number of requested entries in the tpmAggrReportTable only. Because the probe can derive this table from the apmReportTable, the probe must make sure that sufficient resources exist to support the creation of the apmReportTable, plus any additional resources required to convert or support this table. This object may not be modified if the associated tpmReportAggregateCntrlStatus object is equal to active(1).

Unsigned32

The maximum number of performance entries in this report. When the associated tpmAggrReportCntrlReqSize object is created or modified, the probe should set this object as closely to the requested value as is possible for the particular implementation and available resources. The probe must not lower this value except as a result of a set to the associated tpmAggrReportCntrlReqSize object. It is an implementation-specific matter as to whether zero-valued entries are available.

Unsigned32 (1..65535)

The number of saved reports requested to be allocated on behalf of this entry. If the tpmAggrReportCntrlApmCntrlIndex is non-zero, then this object should be set by the agent to the value of the apmReportControlcwRequestedReportsDataSource object. This object may not be modified if the associated tpmReportAggregateCntrlStatus object is equal to active(1).

Unsigned32 (0..65535)

The number of saved reports the agent has allocated based on the requested amount in tpmAggrReportCntrlReqReports. Because each report can have many entries, the total number of entries allocated will be this number multiplied by the value of tpmAggrReportCntrlGrantedSize, or by 1 if that object doesn't exist. When the associated tpmAggrReportCntrlReqReports object is created or modified, the agent should set this object as closely to the requested value as is possible for the particular implementation and available resources. When considering available resources, the agent must consider its ability to allocate this many reports, each with the number of entries represented by tpmAggrReportCntrlGrantedSize, or by 1 if that object doesn't exist. Note that although the storage required for each report may fluctuate due to changing conditions, the agent must continue to have storage available to satisfy the full report size for all reports, when necessary. Further, the agent must not lower this value except as a result of a set to the associated tpmAggrReportCntrlReqSize object.

TimeStampThe value of the sysUpTime object at which a specific occurrence happened. The specific occurrence must be defined in the description of any object defined using this type. If sysUpTime is reset to zero as a result of a re- initialization of the network management (sub)system, then the values of all TimeStamp objects are also reset. However, after approximately 497 days without a re- initialization, the sysUpTime object will reach 2^^32-1 and then increment around to zero; in this case, existing values of TimeStamp objects do not change. This can lead to ambiguities in the value of TimeStamp objects. · TimeTicks

The value of sysUpTime when the system began processing the report in progress. Note that the report in progress is not available. This object may be used by the management station to figure out the start time for all previous reports saved for this tpmAggrReportCntrlEntry, as reports are started at fixed intervals. If the tpmAggrReportCntrlApmCntrlIndex is non-zero, then this object is set to the corresponding apmReportControlTable object in the APM-MIB defined in the IETF's RMONMIB WG.

Unsigned32

The number of the report in progress. When an tpmAggrReportCntrlEntry is activated, the first report will be numbered zero. If the tpmAggrReportCntrlApmCntrlIndex is non-zero, then this object should be set by the agent to the value of the apmReportControlReportNumber object.

Counter32

The number of attempts to add an entry to reports for this TpmAggrReportCntrlEntry that failed because the number of entries would have exceeded tpmAggrReportCntrlGrantedSize. This number is valuable in determining if enough entries have been allocated for reports in light of fluctuating network usage. Note that an entry that is denied will often be attempted again, so this number will not predict the exact number of additional entries needed, but it can be used to understand the relative magnitude of the problem. Also note that there is no ordering specified for the entries in the report; thus, there are no rules for which entries will be omitted when not enough entries are available. As a consequence, the agent is not required to delete 'least valuable' entries first.

Counter32

The total number of frames that were received by the agent and therefore not accounted for in the *StatsDropEvents, but for which the agent chose not to count for this entry for whatever reason. Most often, this event occurs when the agent is out of some resources and decides to shed load from this collection. This count does not include packets that were not counted because they had MAC-layer errors. Note that if the alMatrixTables are not implemented or are inactive because no protocols are enabled in the protocol directory, this value should be 0. Note that, unlike the dropEvents counter, this number is the exact number of frames dropped.

OwnerStringThis data type is used to model an administratively assigned name of the owner of a resource. Implementations must accept values composed of well-formed NVT ASCII sequences. In addition, implementations should accept values composed of well-formed UTF-8 sequences. It is suggested that this name contain one or more of the following: IP address, management station name, network manager's name, location, or phone number. In some cases the agent itself will be the owner of an entry. In these cases, this string shall be set to a string starting with 'monitor'. SNMP access control is articulated entirely in terms of the contents of MIB views; access to a particular SNMP object instance depends only upon its presence or absence in a particular MIB view and never upon its value or the value of related object instances. Thus, objects of this type afford resolution of resource contention only among cooperating managers; they realize no access control function with respect to uncooperative parties. SIZE (0..127) · OCTET STRING

The entity that configured this entry and is therefore using the resources assigned to it. If the tpmAggrReportCntrlApmCntrlIndex is non-zero, then this object should be set by the agent to the value of the apmReportControlReportNumber object. This object may not be modified if the associated tpmReportAggregateCntrlStatus object is equal to active(1).

StorageType1 = other2 = volatile3 = nonVolatile4 = permanent5 = readOnlyDescribes the memory realization of a conceptual row. A row which is volatile(2) is lost upon reboot. A row which is either nonVolatile(3), permanent(4) or readOnly(5), is backed up by stable storage. A row which is permanent(4) can be changed but not deleted. A row which is readOnly(5) cannot be changed nor deleted. If the value of an object with this syntax is either permanent(4) or readOnly(5), it cannot be written. Conversely, if the value is either other(1), volatile(2) or nonVolatile(3), it cannot be modified to be permanent(4) or readOnly(5). (All illegal modifications result in a 'wrongValue' error.) Every usage of this textual convention is required to specify the columnar objects which a permanent(4) row must at a minimum allow to be writable. · Integer32

The storage type of this tpmAggrReportCntrlEntry. If the value of this object is 'permanent', no objects in this row need to be writable.

RowStatus1 = active2 = notInService3 = notReady4 = createAndGo5 = createAndWait6 = destroyThe RowStatus textual convention is used to manage the creation and deletion of conceptual rows, and is used as the value of the SYNTAX clause for the status column of a conceptual row (as described in Section 7.7.1 of [2].) The status column has six defined values: - `active', which indicates that the conceptual row is available for use by the managed device; - `notInService', which indicates that the conceptual row exists in the agent, but is unavailable for use by the managed device (see NOTE below); 'notInService' has no implication regarding the internal consistency of the row, availability of resources, or consistency with the current state of the managed device; - `notReady', which indicates that the conceptual row exists in the agent, but is missing information necessary in order to be available for use by the managed device (i.e., one or more required columns in the conceptual row have not been instanciated); - `createAndGo', which is supplied by a management station wishing to create a new instance of a conceptual row and to have its status automatically set to active, making it available for use by the managed device; - `createAndWait', which is supplied by a management station wishing to create a new instance of a conceptual row (but not make it available for use by the managed device); and, - `destroy', which is supplied by a management station wishing to delete all of the instances associated with an existing conceptual row. Whereas five of the six values (all except `notReady') may be specified in a management protocol set operation, only three values will be returned in response to a management protocol retrieval operation: `notReady', `notInService' or `active'. That is, when queried, an existing conceptual row has only three states: it is either available for use by the managed device (the status column has value `active'); it is not available for use by the managed device, though the agent has sufficient information to attempt to make it so (the status column has value `notInService'); or, it is not available for use by the managed device, and an attempt to make it so would fail because the agent has insufficient information (the state column has value `notReady'). NOTE WELL This textual convention may be used for a MIB table, irrespective of whether the values of that table's conceptual rows are able to be modified while it is active, or whether its conceptual rows must be taken out of service in order to be modified. That is, it is the responsibility of the DESCRIPTION clause of the status column to specify whether the status column must not be `active' in order for the value of some other column of the same conceptual row to be modified. If such a specification is made, affected columns may be changed by an SNMP set PDU if the RowStatus would not be equal to `active' either immediately before or after processing the PDU. In other words, if the PDU also contained a varbind that would change the RowStatus value, the column in question may be changed if the RowStatus was not equal to `active' as the PDU was received, or if the varbind sets the status to a value other than 'active'. Also note that whenever any elements of a row exist, the RowStatus column must also exist. To summarize the effect of having a conceptual row with a status column having a SYNTAX clause value of RowStatus, consider the following state diagram: STATE +--------------+-----------+-------------+------------- | A | B | C | D | |status col.|status column| |status column | is | is |status column ACTION |does not exist| notReady | notInService| is active --------------+--------------+-----------+-------------+------------- set status |noError ->D|inconsist- |inconsistent-|inconsistent- column to | or | entValue| Value| Value createAndGo |inconsistent- | | | | Value| | | --------------+--------------+-----------+-------------+------------- set status |noError see 1|inconsist- |inconsistent-|inconsistent- column to | or | entValue| Value| Value createAndWait |wrongValue | | | --------------+--------------+-----------+-------------+------------- set status |inconsistent- |inconsist- |noError |noError column to | Value| entValue| | active | | | | | | or | | | | | | | |see 2 ->D|see 8 ->D| ->D --------------+--------------+-----------+-------------+------------- set status |inconsistent- |inconsist- |noError |noError ->C column to | Value| entValue| | notInService | | | | | | or | | or | | | | | |see 3 ->C| ->C|see 6 --------------+--------------+-----------+-------------+------------- set status |noError |noError |noError |noError ->A column to | | | | or destroy | ->A| ->A| ->A|see 7 --------------+--------------+-----------+-------------+------------- set any other |see 4 |noError |noError |see 5 column to some| | | | value | | see 1| ->C| ->D --------------+--------------+-----------+-------------+------------- (1) goto B or C, depending on information available to the agent. (2) if other variable bindings included in the same PDU, provide values for all columns which are missing but required, and all columns have acceptable values, then return noError and goto D. (3) if other variable bindings included in the same PDU, provide legal values for all columns which are missing but required, then return noError and goto C. (4) at the discretion of the agent, the return value may be either: inconsistentName: because the agent does not choose to create such an instance when the corresponding RowStatus instance does not exist, or inconsistentValue: if the supplied value is inconsistent with the state of some other MIB object's value, or noError: because the agent chooses to create the instance. If noError is returned, then the instance of the status column must also be created, and the new state is B or C, depending on the information available to the agent. If inconsistentName or inconsistentValue is returned, the row remains in state A. (5) depending on the MIB definition for the column/table, either noError or inconsistentValue may be returned. (6) the return value can indicate one of the following errors: wrongValue: because the agent does not support notInService (e.g., an agent which does not support createAndWait), or inconsistentValue: because the agent is unable to take the row out of service at this time, perhaps because it is in use and cannot be de-activated. (7) the return value can indicate the following error: inconsistentValue: because the agent is unable to remove the row at this time, perhaps because it is in use and cannot be de-activated. (8) the transition to D can fail, e.g., if the values of the conceptual row are inconsistent, then the error code would be inconsistentValue. NOTE: Other processing of (this and other varbinds of) the set request may result in a response other than noError being returned, e.g., wrongValue, noCreation, etc. Conceptual Row Creation There are four potential interactions when creating a conceptual row: selecting an instance-identifier which is not in use; creating the conceptual row; initializing any objects for which the agent does not supply a default; and, making the conceptual row available for use by the managed device. Interaction 1: Selecting an Instance-Identifier The algorithm used to select an instance-identifier varies for each conceptual row. In some cases, the instance- identifier is semantically significant, e.g., the destination address of a route, and a management station selects the instance-identifier according to the semantics. In other cases, the instance-identifier is used solely to distinguish conceptual rows, and a management station without specific knowledge of the conceptual row might examine the instances present in order to determine an unused instance-identifier. (This approach may be used, but it is often highly sub-optimal; however, it is also a questionable practice for a naive management station to attempt conceptual row creation.) Alternately, the MIB module which defines the conceptual row might provide one or more objects which provide assistance in determining an unused instance-identifier. For example, if the conceptual row is indexed by an integer-value, then an object having an integer-valued SYNTAX clause might be defined for such a purpose, allowing a management station to issue a management protocol retrieval operation. In order to avoid unnecessary collisions between competing management stations, `adjacent' retrievals of this object should be different. Finally, the management station could select a pseudo-random number to use as the index. In the event that this index was already in use and an inconsistentValue was returned in response to the management protocol set operation, the management station should simply select a new pseudo-random number and retry the operation. A MIB designer should choose between the two latter algorithms based on the size of the table (and therefore the efficiency of each algorithm). For tables in which a large number of entries are expected, it is recommended that a MIB object be defined that returns an acceptable index for creation. For tables with small numbers of entries, it is recommended that the latter pseudo-random index mechanism be used. Interaction 2: Creating the Conceptual Row Once an unused instance-identifier has been selected, the management station determines if it wishes to create and activate the conceptual row in one transaction or in a negotiated set of interactions. Interaction 2a: Creating and Activating the Conceptual Row The management station must first determine the column requirements, i.e., it must determine those columns for which it must or must not provide values. Depending on the complexity of the table and the management station's knowledge of the agent's capabilities, this determination can be made locally by the management station. Alternately, the management station issues a management protocol get operation to examine all columns in the conceptual row that it wishes to create. In response, for each column, there are three possible outcomes: - a value is returned, indicating that some other management station has already created this conceptual row. We return to interaction 1. - the exception `noSuchInstance' is returned, indicating that the agent implements the object-type associated with this column, and that this column in at least one conceptual row would be accessible in the MIB view used by the retrieval were it to exist. For those columns to which the agent provides read-create access, the `noSuchInstance' exception tells the management station that it should supply a value for this column when the conceptual row is to be created. - the exception `noSuchObject' is returned, indicating that the agent does not implement the object-type associated with this column or that there is no conceptual row for which this column would be accessible in the MIB view used by the retrieval. As such, the management station can not issue any management protocol set operations to create an instance of this column. Once the column requirements have been determined, a management protocol set operation is accordingly issued. This operation also sets the new instance of the status column to `createAndGo'. When the agent processes the set operation, it verifies that it has sufficient information to make the conceptual row available for use by the managed device. The information available to the agent is provided by two sources: the management protocol set operation which creates the conceptual row, and, implementation-specific defaults supplied by the agent (note that an agent must provide implementation-specific defaults for at least those objects which it implements as read-only). If there is sufficient information available, then the conceptual row is created, a `noError' response is returned, the status column is set to `active', and no further interactions are necessary (i.e., interactions 3 and 4 are skipped). If there is insufficient information, then the conceptual row is not created, and the set operation fails with an error of `inconsistentValue'. On this error, the management station can issue a management protocol retrieval operation to determine if this was because it failed to specify a value for a required column, or, because the selected instance of the status column already existed. In the latter case, we return to interaction 1. In the former case, the management station can re-issue the set operation with the additional information, or begin interaction 2 again using `createAndWait' in order to negotiate creation of the conceptual row. NOTE WELL Regardless of the method used to determine the column requirements, it is possible that the management station might deem a column necessary when, in fact, the agent will not allow that particular columnar instance to be created or written. In this case, the management protocol set operation will fail with an error such as `noCreation' or `notWritable'. In this case, the management station decides whether it needs to be able to set a value for that particular columnar instance. If not, the management station re-issues the management protocol set operation, but without setting a value for that particular columnar instance; otherwise, the management station aborts the row creation algorithm. Interaction 2b: Negotiating the Creation of the Conceptual Row The management station issues a management protocol set operation which sets the desired instance of the status column to `createAndWait'. If the agent is unwilling to process a request of this sort, the set operation fails with an error of `wrongValue'. (As a consequence, such an agent must be prepared to accept a single management protocol set operation, i.e., interaction 2a above, containing all of the columns indicated by its column requirements.) Otherwise, the conceptual row is created, a `noError' response is returned, and the status column is immediately set to either `notInService' or `notReady', depending on whether it has sufficient information to (attempt to) make the conceptual row available for use by the managed device. If there is sufficient information available, then the status column is set to `notInService'; otherwise, if there is insufficient information, then the status column is set to `notReady'. Regardless, we proceed to interaction 3. Interaction 3: Initializing non-defaulted Objects The management station must now determine the column requirements. It issues a management protocol get operation to examine all columns in the created conceptual row. In the response, for each column, there are three possible outcomes: - a value is returned, indicating that the agent implements the object-type associated with this column and had sufficient information to provide a value. For those columns to which the agent provides read-create access (and for which the agent allows their values to be changed after their creation), a value return tells the management station that it may issue additional management protocol set operations, if it desires, in order to change the value associated with this column. - the exception `noSuchInstance' is returned, indicating that the agent implements the object-type associated with this column, and that this column in at least one conceptual row would be accessible in the MIB view used by the retrieval were it to exist. However, the agent does not have sufficient information to provide a value, and until a value is provided, the conceptual row may not be made available for use by the managed device. For those columns to which the agent provides read-create access, the `noSuchInstance' exception tells the management station that it must issue additional management protocol set operations, in order to provide a value associated with this column. - the exception `noSuchObject' is returned, indicating that the agent does not implement the object-type associated with this column or that there is no conceptual row for which this column would be accessible in the MIB view used by the retrieval. As such, the management station can not issue any management protocol set operations to create an instance of this column. If the value associated with the status column is `notReady', then the management station must first deal with all `noSuchInstance' columns, if any. Having done so, the value of the status column becomes `notInService', and we proceed to interaction 4. Interaction 4: Making the Conceptual Row Available Once the management station is satisfied with the values associated with the columns of the conceptual row, it issues a management protocol set operation to set the status column to `active'. If the agent has sufficient information to make the conceptual row available for use by the managed device, the management protocol set operation succeeds (a `noError' response is returned). Otherwise, the management protocol set operation fails with an error of `inconsistentValue'. NOTE WELL A conceptual row having a status column with value `notInService' or `notReady' is unavailable to the managed device. As such, it is possible for the managed device to create its own instances during the time between the management protocol set operation which sets the status column to `createAndWait' and the management protocol set operation which sets the status column to `active'. In this case, when the management protocol set operation is issued to set the status column to `active', the values held in the agent supersede those used by the managed device. If the management station is prevented from setting the status column to `active' (e.g., due to management station or network failure) the conceptual row will be left in the `notInService' or `notReady' state, consuming resources indefinitely. The agent must detect conceptual rows that have been in either state for an abnormally long period of time and remove them. It is the responsibility of the DESCRIPTION clause of the status column to indicate what an abnormally long period of time would be. This period of time should be long enough to allow for human response time (including `think time') between the creation of the conceptual row and the setting of the status to `active'. In the absence of such information in the DESCRIPTION clause, it is suggested that this period be approximately 5 minutes in length. This removal action applies not only to newly-created rows, but also to previously active rows which are set to, and left in, the notInService state for a prolonged period exceeding that which is considered normal for such a conceptual row. Conceptual Row Suspension When a conceptual row is `active', the management station may issue a management protocol set operation which sets the instance of the status column to `notInService'. If the agent is unwilling to do so, the set operation fails with an error of `wrongValue' or `inconsistentValue'. Otherwise, the conceptual row is taken out of service, and a `noError' response is returned. It is the responsibility of the DESCRIPTION clause of the status column to indicate under what circumstances the status column should be taken out of service (e.g., in order for the value of some other column of the same conceptual row to be modified). Conceptual Row Deletion For deletion of conceptual rows, a management protocol set operation is issued which sets the instance of the status column to `destroy'. This request may be made regardless of the current value of the status column (e.g., it is possible to delete conceptual rows which are either `notReady', `notInService' or `active'.) If the operation succeeds, then all instances associated with the conceptual row are immediately removed. · Integer32

The status of this performance control entry. An entry may not exist in the active state unless each object in the entry has an appropriate value. If the tpmAggrReportCntrlApmCntrlIndex is non-zero, then this object should be set by the agent to the value of the apmReportControlReportNumber object. Once this object is set to active(1), no objects in the tpmAggrReportCntrlTable can be changed. If this object is not equal to active(1), all associated entries in the tpmAggrReportTable shall be deleted.

AppLocalIndexA locally arbitrary unique identifier associated with an application or application verb. All objects of type AppLocalIndex are assigned by the agent out of a common number space. In other words, AppLocalIndex values assigned to entries in one table must not overlap with AppLocalIndex values assigned to entries in another table. Further, every protocolDirLocalIndex value registered by the agent automatically assigns the same value out of the AppLocalIndex number space. For example, if the protocolDirLocalIndex values { 1, 3, 5, 7 } have been assigned, and the apmHttpFilterAppLocalIndex values { 6, 8, 9 } have been assigned: - Assignment of new AppLocalIndex values must not use the values { 1, 3, 5, 6, 7, 8, 9 }. - AppLocalIndex values { 1, 3, 5, 7 } are automatically assigned and are associated with the identical value of protocolDirLocalIndex. In particular, an entry in the apmAppDirTable indexed by a value provides further information about a protocol indexed by the same value in the protocolDirTable of RMON2. The value for each supported application must remain constant at least from one re-initialization of the entity's network management system to the next re-initialization, except that if an application is deleted and re-created, it must be re-created with a new value that has not been used since the last re-initialization. The specific value is meaningful only within a given SNMP entity. An AppLocalIndex value must not be re-used until the next agent restart. (1..2147483647) · Unsigned32

OCTET STRING SIZE (0..108)

The network layer address of the server host in this conversation. This is represented as an octet string with specific semantics and length as identified by the protocolDirLocalIndex component of the index. Because this object is an index variable, it is encoded in the index according to the index encoding rules. For example, if the protocolDirLocalIndex indicates an encapsulation of IPv4, this object is encoded as a length octet of 4, followed by the 4 octets of the IPv4 address, in network byte order. If the associated tpmAggrReportCntrlAggrType is equal to application(4) or client(2), then this object will be a null string and will be encoded simply as a length octet of 0.

RmonClientIDA long-lived unique ID assigned to an end-system. This ID is assigned by the agent using an implementation-specific algorithm. Because a client machine may be assigned multiple addresses over any time period it can be difficult to attribute behavior to a particular client based solely on its address. A ClientID may be assigned to provide a more stable handle for referencing that client. The entity that assigns the ClientID may use various implementation techniques to keep track of a client but if the assigning entity is unable to track client address mappings, it may map client identifiers to client addresses rather than to distinct client machines. This is named ClientID because it helps to solve a problem seen in network clients (servers usually have well-known, long-lived addresses). However, ClientID's may be assigned to any end-system regardless of its role on the network. · Unsigned32

The status of this transaction. It is not always obvious from context whether a transaction is ongoing or completed. E.g., an ftp-GET transaction may last several minutes or hours, and a value found in the tpmCurReportMetricValue object lists to observed throughput for the transaction up to this point in time. The value of the tpmCurReportCompletion indicates whether the transaction has been completed.

TpmTransactionMetricIndexAn index used to identify an entry in the tpmTransMetricDir table uniquely. Each such entry defines the protocol transaction and metric instance to be monitored for a specific application. (1..65535) · Unsigned32 · hint d

A unique index that identifies the transaction and metric associated with the data reported here.

ZeroBasedCounter32This TC describes an object that counts events with the following semantics: objects of this type will be set to zero(0) on creation and will thereafter count appropriate events, wrapping back to zero(0) when the value 2^32 is reached. Provided that an application discovers the new object within the minimum time to wrap, it can use the initial value as a delta since it last polled the table of which this object is part. It is important for a management station to be aware of this minimum time and the actual time between polls, and to discard data if the actual time is too long or there is no defined minimum time. Typically, this TC is used in tables where the INDEX space is constantly changing and/or the TimeFilter mechanism is in use. · Gauge32

The count of the total number of data points for the specified metric. This number always represents the total size of the statistical datum analyzed. Each metric specifies the exact meaning of this object. This value represents the results of one metric and is related directly to the specific parameters of the metric and the Server and Client addresses involved.
