PRTG Probe Service running at 80 - 90% CPU utilization



This seems to happen each afternoon (possibly more often that than). I get a warning from PRTG: 97 % (System CPU Load) is above the error limit of 90 % in System CPU Load. How can I figure out what is causing this?

Hello there,

Are there any other application running or any schedule, antivirus scanning or windows update patches installation on this timeframe? It might be possible due to that cpu load increase and you are getting a warning about this.

I would also suggest you discuss this type of issue in the support ticket. Because, it's really difficult to discuss this issue over the KB post as we require the sensor screenshot, support bundle etc. to analyze this issue further. Please feel free to contact at [email protected]
