In cases where a manager must obtain performance history data about
the behavior of equipment it manages several strategies can be

equipment, including:
0 The agent counts events on a continuous basis and,
whenever desired, the manager obtains the value of the event
counter and adjusts its understanding of the history of events
at the agent.
0 The agent allocates events to 'buckets' where each bucket
represents an interval of time.
Telecommunications equipment often makes use of the latter strategy.
See [3][4][5] for examples. In particular, for this equipment it is
common that history data is maintained by the agent in terms of
fifteen minute intervals.
