NetXMS Support Forum

hi,

Total number of objects: 62219
Number of monitored nodes: 1347
Number of collectable DCIs: 1354

cpu usage is really high, it seems like it's even higher as soon as a console-client connects:

CPU: Intel(R) Pentium(R) Dual  CPU  E2200  @ 2.20GHz

disk io, and memory seems to be ok.

i'm using postgres (tried 8.4 and 9.1) on ubuntu 12.04

what's your recommendation for NumberOf*Pollers?

Hi!

Can you show how a chart of CPU usage on your NetXMS server? It seems quite strange to have very high CPU usage on that number of nodes. Regarding number of pollers, I would suggest to set it as following:

NumberOfConfigurationPollers = 20
NumberOfDatabaseWriters = 4 (or more if database writer queue still big)
NumberOfDataCollectors = 50
NumberOfRoutingTablePollers = 20
NumberOfStatusPollers = 50
NumberOfTopologyPollers = 20

High CPU usage may be caused by frequent polling of large routing tables. For example, if you have a router with full BGP table, it is recommended to turn off routing table polling for it, otherwise NetXMS server will try to fetch this huge table periodically.

Best regards,
Victor

thx,

is it possible to turn of routing table pollig  by default, e.g.  for s specific sysobjectid or any other filter? or should i do this with a nxshell script?
