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

::= { mib-2 58 }
|
|
|
|
|
|
-- The Textual Conventions defined below are organized
|
|
-- alphabetically
|
|
|
|
-- Use of these TCs assumes the following:
|
|
-- 0 The agent supports 15 minute based history
|
|
-- counters.
|
|
-- 0 The agent is capable of keeping a history of n
|
|
-- intervals of 15 minute performance data. The
|
|
-- value of n is defined by the specific MIB
|
|
-- module but shall be 0 < n =< 96.
|
|
-- 0 The agent may optionally support performance
|
|
-- data aggregating the history intervals.
|
|
-- 0 The agent will keep separate tables for the
|
|
-- current interval, the history intervals, and
|
|
-- the total aggregates.
|
|
-- 0 The agent will keep the following objects.
|
|
-- If performance data is kept for multiple instances
|
|
-- of a measured entity, then
|
|
-- these objects are applied to each instance of
|
|
-- the measured entity (e.g., interfaces).

DESCRIPTION
|
|
"A counter associated with a
|
|
performance measurement in a current 15
|
|
minute measurement interval. The value
|
|
of this counter 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 counter is
|
|
stored in the first 15 minute history
|
|
interval, and the CurrentCount 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 (for example, a noSuchName
|
|
error for SNMPv1 and a noSuchInstance for
|
|
SNMPv2 GET operation)."

DESCRIPTION
|
|
"A counter 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 (for example, a noSuchName
|
|
error for SNMPv1 and a noSuchInstance for
|
|
SNMPv2 GET operation).
|
|
In a system supporting
|
|
a history of n intervals with
|
|
IntervalCount(1) and IntervalCount(n) the
|
|
most and least recent intervals
|
|
respectively, the following applies at
|
|
the end of a 15 minute interval:
|
|
- discard the value of IntervalCount(n)
|
|
- the value of IntervalCount(i) becomes that
|
|
of IntervalCount(i-1) for n >= i > 1
|
|
- the value of IntervalCount(1) becomes that
|
|
of CurrentCount
|
|
- the TotalCount, if supported, is adjusted."
