I am looking to reduce the CPU usage on my PRTG probe. My PRTG hardware is a few years old and it's spiking past 85% utilization at least once a day. I have about 400 sensors on 97 devices.
My first thought is to reduce the amount of probes that it's monitoring, so I'm looking for some direction on disabling which probes will benefit me the most.
One one server, for instance, I have PING, CPU LOAD, DISK FREE, MEMORY UTILIZATION, UPTIME, and RDP. Are all of those things being reported at the same time by a single query? On that particular server, UPTIME and MEMORY UTILIZATION aren't as important as the others, so I'd be fine deleting those probes. However if it's all "reported at the same time" as part of a single query I have my doubts that fine-grain tuning of the probes by removing one or two per server will make any difference in CPU utilization.
Any ideas or thoughts? Any particular probe categories that take up more CPU use than others that I should think about removing first? Thanks!
