Ok, this may be beating a dead horse. I've found many articles related to PRTG/WMI sensors. But I feel like this should work, or at least I feel like I'm way under some of the limits described in these articles.
I have a dedicated server, 16 cores, 24GB RAM, 4 10k SAS drives, 2 1Gb nics in a team.
in total I have the following WMI sensors configured: 4x wmicustom, 12x wmidiskspace, 3x wmiexchangeserver, 3x wmilogicaldisk, 57x wmimemory, 16x wminetwork, 57x wmiprocessor, 3x wmiterminalservices, 41x wmiterminalservices2008
now that is more than a hundred but not thousands, furthermore, most of these are paused.
Currently I have 10 sensors enabled. And currently my Interval Delay WMI is at 0%. but just within the last 20min there was one period where that was at 57%.
This is all after I reduced the frequency of these sensors from 60s to 5m. (yesterday I set these all to 5m and resumed the lot. today the were a mix of red/yellow/gray)
I guess setting up local probes on each server may be an option (but I have 100+ servers to monitor so that would be painful)
I feel like I have the hardware, it is certainly idling. No I have plenty of other software in the environment. SCOM, scripts, etc. but the individual sensors work when not enabled all at once, so I assume it's not an issue on the far end.
any help would be much appreciated!
