How do I check for performance monitoring statistics collection?

Process

Use the performance monitoring statistic log records to determine whether performance statistics are collected within the scheduled interval using the client GUI.

 
1 

Choose Tools→Statistics→Statistics Manager from the NFM-P main menu. The Statistics Manager form opens.

2 

Set the Statistics Type parameter to Statistics Record to retrieve a list of historical data for the type of logged statistics.

3 

Choose a type of statistics to collect. For example, to check interface statistics for managed devices, choose Interface Additional Stats (Physical Equipment).

4 

Perform one of the following:

  1. To collect statistics for the past hour, click Search. Go to Step 6 .

  2. To collect statistics based on a set of user-defined criteria, choose No Filter.

5 

Configure the filter criteria and click Search.

Note: You must specify a filter to limit the number of log records to less than 15 000; otherwise, a problem encountered form appears.

6 

Review the data for the selected statistic.

  1. Click on the Monitored Object or Monitored Object Name headings to sort the historical statistics records by type of object.

  2. Review the Time Captured heading for one or more objects.

    Verify that the time captured intervals match the intervals set for the object or the statistic logging class.

    If the time captured intervals are not sufficient, there will be gaps in the historical record.

7 

If there are gaps in the historical record, check the mediation policy to ensure that:

  • polling is enabled and administratively up

  • the polling interval for a specific MIB or MIB entry is sufficient for collecting the required statistics

Note: Each row that represents a log record shows the Suspect column. When a check mark is present for an interval, there may have been a problem with collection during that interval.

8 

Record the data for the selected device and type of statistics. Use this data as a base measurement to verify that statistics data was collected correctly over the scheduled interval.
