DESCRIPTION
|
|
"This MIB Module provides Textual Conventions to be
|
|
used by systems supporting 15 minute based performance
|
|
history counts that require high-capacity counts.
|

|
Copyright (C) The Internet Society (2004). This version
|
|
of this MIB module is part of RFC 3705: see the RFC

HCPerfValidIntervals ::= TEXTUAL-CONVENTION
|
|
STATUS current
|
|
DESCRIPTION
|
|
"The 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."

HCPerfInvalidIntervals ::= TEXTUAL-CONVENTION
|
|
STATUS current
|
|
DESCRIPTION
|
|
"The number of near end intervals for which no data is
|
|
available. The value of an object with an
|
|
HCPerfInvalidIntervals syntax will typically be zero except
|
|
in cases where the data for some intervals are not available
|
|
(e.g., in proxy situations)."

HCPerfTimeElapsed ::= TEXTUAL-CONVENTION
|
|
STATUS current
|
|
DESCRIPTION
|
|
"The 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)."

HCPerfIntervalThreshold ::= TEXTUAL-CONVENTION
|
|
STATUS current
|
|
DESCRIPTION
|
|
"This convention defines a range of values that may be set
|
|
in a fault threshold alarm control. As the number of
|
|
seconds in a 15-minute interval numbers at most 900,
|
|
objects of this type may have a range of 0...900, where the
|
|
value of 0 disables the alarm."

|
SYNTAX Unsigned32 (0..900)
|
|
|
|
HCPerfCurrentCount ::= TEXTUAL-CONVENTION
|
|
STATUS current
|
|
DESCRIPTION
|
|
"A 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."

HCPerfIntervalCount ::= TEXTUAL-CONVENTION

STATUS current
|
|
DESCRIPTION
|
|
"A 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

|
decreases below 2^64-1 (due, e.g., to a retroactive

DESCRIPTION
