Statistics management in the NFM-P

Overview

The NFM-P provides a scalable platform for reliable statistics collection from managed NEs, and also provides statistics for monitoring NFM-P system processes and functions.

Depending on the statistics type, you can do the following with the collected data:

Note: Before you configure statistics collection, you must consider the NFM-P resource constraints; see  NFM-P statistics scalability for general information, and the NSP Planning Guide for release-specific scalability guidelines.

The NFM-P can collect the following statistics types:

See NFM-P statistics types for more information about each statistic type.

Policy-based collection

To collect statistics such as NE performance or accounting statistics, the NFM-P uses policies that specify the following:

From the Statistics tab of an object properties form, you can use the following buttons to perform an on-demand collection of network or server performance statistics:

Note: On-demand statistics collection may yield inconsistent results the first time it is run against an object. To obtain valid results, you must run the on-demand statistics collection more than once.

Statistics are stored for a configurable retention period that is defined in an NFM-P statistics policy. When the retention period elapses, the statistics are removed. However, statistics that are collected for real-time display are not stored; the statistics are available only for the duration of the current session, and only for the operator that initiates the session.
