Network Performance Monitor (NPM)
Polling Interval Change
clerum
OK-
What I am trying to accomplish is different polling intervals for different devices/interfaces. So I have added a custom property called Service_Level, and added to Interfaces and Nodes. Now I go into the "Network Preformance Monitor Settings" and change the default poll interval for nodes to 120 seconds. I also set the statistic collection interval to 5 minutes.
Now I have some core nodes I want to have polled every 10 sec and intefaces I want stats on @ 1 min intervals.
So I hope in and do my sql statements like so
update nodes set pollinterval=10 where service_level=0;
update interfaces set statcollection=1 where service_level=0;
update nodes set pollinterval=60 where service_level=10;
update interfaces set pollinterval=60 where service_level=0;
I can verify from the website that things have been updated. But then in no time @ all it appears the changes have reverted. I'm doing this with the SQL Server Enterprise Manager, I don't see that I have to type commit...what am I missing, or is orion just overwriting my changes?

Have you stopped & restarted the Solarwinds Poller service?
BTW, with those polling times, you are really going to tax the server and grow the DB in a hurry. Make sure you re-run the polling engine tuning app, as your polls per second will need to go waaaaay up.
Also - be prepared for false alerts with those kind of polling intervals.

Yep, that's exactly right.
You need to shutdown the "SolarWinds Network Performance Monitor" service before making those kind of changes to the database.
It keeps an in memory model of the network and syncs it to the database every few minutes.
So... shutdown the service. Make your changes, and restart it.

I'm actually running quite solid with those aggressive rates accross 299 Nodes and 475 interfaces.
Now I'm trying to scale those aggressive rates down to just a few core nodes, and go more lax on others as I adding more customer's into the system while we migrate away from HP Openview.
