I'm trying to get an idea of what the optimal polling interval and statistics collection interval would be based on the number of nodes and interfaces. I was hoping we could get a thread going with everyone's polling configuration along with the server Orion is running on. One of the main problems with our previous NMS was that it was overtaxed, resulting in a lot of false alarms. Here is what I've got.
Network Nodes - 722, Interfaces - 1199, Volumes - 483
I've got the majority of my devices configured to poll every 120 seconds and statistics at 10 minutes. Approximately 50 critical devices are being polled every 60 seconds and statistics every 5 minutes.
Quad-Core Xeon 64-bit running Server 2k3 32-bit w/ 4GB RAM.
