Health Monitor MIB module. The Health Monitor uses a model based on events of varying severity and frequency, and predefined rules, to generate a metric that represents a system's (and its subsystems') level of health. The events are typically internally generated notifications in response to detrimental or correctional changes in the state of the hardware or software of the system. Detrimental events are classified under one of the following severity levels: Catastrophic - Causes or leads to system failure Critical - Major subsystem or functionality failure High - Potential for major impact to important functions Medium - Potential for minor impact to functionality Low - Negligible impact to functionality Whilst correctional events fall under the following classification: Positive - Not a fault event. May cause or lead to the return of functionality This MIB module provides information for tracking occurrences of the above events, and presents the associated health metric for the system and its component subsystems.

This table contains Health Monitor statistics for physical entities and their constituent hardware and/or software subsystems. The Health Monitor statistics present in each row provide information such as the computed health of the indicated subsystem and the number of faults it has experienced.
from ENTITY-MIB
PhysicalIndexAn arbitrary value that uniquely identifies the physical entity. The value should be a small positive integer. Index values for different physical entities are not necessarily contiguous. (1..2147483647) · Integer32 · hint d
The index for this entry.
1.3.6.1.4.1.9.9.243.1.1.1.1
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 (1..128) · OCTET STRING · hint 255t
A textual string containing the name of the hardware or software subsystem. A management station wishing to obtain summary statistics for a physical entity should use a value of 'system' for this object.

HealthLevelReflects the health of a system or subsystem based on system events and predefined rules, expressed as a percentage. The UNITS clause associated with each object will indicate the degree of precision. (0..10000) · Gauge32 · 0.01 percent
The computed current health of this subsystem on the specified entity. This health metric is based on predefined rules that specify how the health should be adjusted in response to certain events of varying severity and frequency. As these events are encountered by each subsystem or physical entity, the appropriate rules are applied and the health is modified accordingly.
1.3.6.1.4.1.9.9.243.1.1.1.3
TruthValue1 = true2 = falseRepresents a boolean value. · Integer32
Enables or disables health level notifications. When set to true(1), the ciscoHealthMonitorHealthLevel notification is enabled. When set to false(0), the ciscoHealthMonitorHealthLevel notification is disabled. If such a notification is desired, it is the responsibility of the management entity to ensure that the SNMP administrative model is configured in such a way as to allow the notification to be delivered.
1.3.6.1.4.1.9.9.243.1.1.1.4
HealthLevelReflects the health of a system or subsystem based on system events and predefined rules, expressed as a percentage. The UNITS clause associated with each object will indicate the degree of precision. (0..10000) · Gauge32 · 0.01 percent
Specifies the health level at which a ciscoHealthMonitorHealthLevel notification will be generated for the specified subsystem and entity. A notification will only be generated if the health level had previously reached the low threshold level prior to reaching this high threshold level. Health levels oscillating within the high and the low threshold levels do not generate notifications. A health level going from low threshold (or below) to high threshold (or above) represents a return to normal health for the specified subsystem. Set your optimal health level to this threshold.

HealthLevelReflects the health of a system or subsystem based on system events and predefined rules, expressed as a percentage. The UNITS clause associated with each object will indicate the degree of precision. (0..10000) · Gauge32 · 0.01 percent
Specifies the health level at which a ciscoHealthMonitorHealthLevel notification will be generated for the specified subsystem and entity. A notification will only be generated if the health level had previously reached the high threshold level prior to reaching this low threshold level. Health levels oscillating within the high and the low threshold levels do not generate notifications. A health level going from high threshold (or above) to low threshold (or below) represents a deterioration of the health for the specified subsystem. Set your unacceptable health level to this threshold.
