I'm running the probes on Hyper-V machinery. My primary probe has begun alerting me of high CPU utilization (health sensor). As it runs as a Hyper-V I've gone into the Hyper-V host, and looked on the CPU load for the PRTG probe, and that reports 1-2% CPU load? We've changed a LOT of our WMI sensors to SNMP sensors to lessen the load, and make the checks more stable (we're not that thrilled with WMI), especially for our clustered environments we get better results with SNMP after a node switch.
My Probe goes high in CPU utlization, while the machine it runs on says 1%???
