          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).

     --       "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

     --       some data. In certain cases (e.g., in the case
     --       where the agent is a proxy) it is possible that some

              "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

              "A counter associated with a

               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."
