Polling interval for a specific volume not changing?

automag928 Jun 28, 2013 7:53 AM

In NPM, I'm trying to monitor the disk utilization of a particular volume, but I would like change the statistics gathering from 30 minutes to 15. However, when I attempt to edit that specific volume and change the Polling times, Collect statistics is currently shown at every 15 minutes however the data is only being pulled every 30 minutes still. Also if I try to edit the specific volume and change the Poll for topology data from 30 minutes to anything else, it does not register the change. Hopefully this makes sense but here's some screenshots.

What does the database show?

SELECT * FROM Volumes (nolock) WHERE Caption LIKE '%ss2bv4p-dc%'

The "StatCollection" column should show you the current polling interval. The default for NPM is 15 minutes, and your screenshots look accurate, so I am not sure why you're only getting results every 30.

Yep I thought of that, stat collection is 15, rediscovery is 30, poll interval is 120 in the volumes DB

  I guess the next question would be where are your seeing/how did you determine, that you are only getting results every 30 minutes?

    It is a good point. Edit the chart resource and see "Sample interval" settings. By default it is 30 minutes.
