Problem: Statistics are rolling over too quickly
Problem
Statistics database tables roll over, or lose statistics during an interval, if the tables fill before all statistics are collected or the next collection interval starts.
Solution
To ensure sufficient statistics collection, consider the following:
-
the statistics table size, depending on the configuration specified in the NSP Installation and Upgrade Guide
-
the number of statistics collected, the number of objects with statistics collection enabled, and the frequency of statistics collection, as specified in the NSP NFM-P Classic Management User Guide
-
the OSS requests data from the statistics tables less frequently than the configured rollover interval
-
FTP must be enabled on the managed device in order for the NFM-P to retrieve statistics.
Nokia recommends that statistics collection planning includes the following considerations to prevent the loss of statistics data.
