HCPerfValidIntervalsThe number of near end intervals for which data was collected. The value of an object with an HCPerfValidIntervals syntax will be 96 unless the measurement was (re-)started within the last 1440 minutes, in which case the value will be the number of complete 15 minute intervals for which the agent has at least some data. In certain cases (e.g., in the case where the agent is a proxy) it is possible that some intervals are unavailable. In this case, this interval is the maximum interval number for which data is available. (0..96) · Integer32

The value of this object will be 96 or the maximum number of 15-minute history intervals collected by the implementation, unless the measurement was (re)started recently, in which case the value will be the number of complete 15-minute intervals for which there are at least some data.

HCPerfTimeElapsedThe number of seconds that have elapsed since the beginning of the current measurement period. If, for some reason, such as an adjustment in the system's time-of-day clock or the addition of a leap second, the duration of the current interval exceeds the maximum value, the agent will return the maximum value. For 15 minute intervals, the range is limited to (0..899). For 24 hour intervals, the range is limited to (0..86399). (0..86399) · Integer32 · seconds

HCPerfCurrentCountA gauge associated with a performance measurement in a current 15 minute measurement interval. The value of an object with an HCPerfCurrentCount syntax starts from zero and is increased when associated events occur, until the end of the 15 minute interval. At that time the value of the gauge is stored in the first 15 minute history interval, and the gauge is restarted at zero. In the case where the agent has no valid data available for the current interval, the corresponding object instance is not available and upon a retrieval request a corresponding error message shall be returned to indicate that this instance does not exist. This count represents a non-negative integer, which may increase or decrease, but shall never exceed 2^64-1 (18446744073709551615 decimal), nor fall below 0. The value of an object with HCPerfCurrentCount syntax assumes its maximum value whenever the underlying count exceeds 2^64-1. If the underlying count subsequently decreases below 2^64-1 (due, e.g., to a retroactive adjustment as a result of entering or exiting unavailable time), then the object's value also decreases. Note that this TC is not strictly supported in SMIv2, because the 'always increasing' and 'counter wrap' semantics associated with the Counter64 base type are not preserved. It is possible that management applications which rely solely upon the (Counter64) ASN.1 tag to determine object semantics will mistakenly operate upon objects of this type as they would for Counter64 objects. This textual convention represents a limited and short- term solution, and may be deprecated as a long term solution is defined and deployed to replace it.

A read-only value specifying the maximum downstream differential delay between all operational BCEs in the GBS, as perceived by its peer port, measured in units of 0.1 ms, during the 15-minute performance history interval. Note that the current max downstream differential delay is indicated by the g9981PortStatMaxDnDiffDelay object. This object is inhibited during Unavailable Seconds (UAS). ⓘ

TruthValue1 = true2 = falseRepresents a boolean value. · Integer32

A read-only object indicating whether or not this history bucket contains valid data. A valid bucket is reported as true(1) and an invalid bucket as false(2). If this history bucket is invalid, the BTU MUST NOT produce notifications based upon the value of the counters in this bucket. Note that an implementation may decide not to store invalid history buckets in its database. In such a case, this object is not required, as only valid history buckets are available while invalid history buckets are simply not in the database. This object partially maps to the TR-159 attribute aGroupPerf15MinIntervalValid. ⓘ

Unsigned32 (1..7)

Performance data interval number. 1 is the most recent previous interval; interval 7 is 24 hours ago. Intervals 2..7 are OPTIONAL. This object partially maps to the TR-159 attribute aGroupPerf1DayIntervalNumber. ⓘ

HCPerfTimeElapsedThe number of seconds that have elapsed since the beginning of the current measurement period. If, for some reason, such as an adjustment in the system's time-of-day clock or the addition of a leap second, the duration of the current interval exceeds the maximum value, the agent will return the maximum value. For 15 minute intervals, the range is limited to (0..899). For 24 hour intervals, the range is limited to (0..86399). (0..86399) · Integer32 · seconds

A count of seconds over which the performance data was actually monitored. This value will be the same as the interval duration (86400 seconds), except in a situation where performance data could not be collected for any reason. This object partially maps to the TR-159 attribute aGroupPerf1DayIntervalMoniSecs. ⓘ

HCPerfIntervalCountA gauge associated with a performance measurement in a previous 15 minute measurement interval. In the case where the agent has no valid data available for a particular interval, the corresponding object instance is not available and upon a retrieval request a corresponding error message shall be returned to indicate that this instance does not exist. Let X be an object with HCPerfIntervalCount syntax. Let Y be an object with HCPerfCurrentCount syntax. Let Z be an object with HCPerfTotalCount syntax. Then, in a system supporting a history of n intervals with X(1) and X(n) the most and least recent intervals respectively, the following applies at the end of a 15 minute interval: - discard the value of X(n) - the value of X(i) becomes that of X(i-1) for n >= i > 1 - the value of X(1) becomes that of Y. - the value of Z, if supported, is adjusted. This count represents a non-negative integer, which may increase or decrease, but shall never exceed 2^64-1 (18446744073709551615 decimal), nor fall below 0. The value of an object with HCPerfIntervalCount syntax assumes its maximum value whenever the underlying count exceeds 2^64-1. If the underlying count subsequently decreases below 2^64-1 (due, e.g., to a retroactive adjustment as a result of entering or exiting unavailable time), then the value of the object also decreases. Note that this TC is not strictly supported in SMIv2, because the 'always increasing' and 'counter wrap' semantics associated with the Counter64 base type are not preserved. It is possible that management applications which rely solely upon the (Counter64) ASN.1 tag to determine object semantics will mistakenly operate upon objects of this type as they would for Counter64 objects.
