WMI Sensors dont work for specific hosts at specific time. Almost every day, at specific time, WMI sensors for specific hosts don't work (are down). They go UP after a few minutes. I added SNMP sensors for same hosts, and they don't get to DOWN state.
On one host the error is always the same: (WMI) "hostname - Windows CPU Load (Windows CPU Load) " "WMI: Device sends inconsistent counter data. Please switch to alternative query in WMI compatibility options. (code: PE041) -- PerfCounter: Could not log in using the specified credentials. Please make sure they are not only valid for the target system, but for the probe system as well. (Performance Counter error 0xB0000004) "
On another host, all (WMI) sensors go down (exchange, cpu, etc..): For example: 1. [PRTG Network Monitor] host1 Windows Pagefile 30 (Windows Pagefile) Down ESCALATION (WMI: Connection could not be established (Timeout during establishing - Host: smtp01.uniqa.hr, User: administrator, Pass...)
2. [PRTG Network Monitor] host1 WMI Free Disk Space (Multi Disk) 30 (WMI Free Disk Space (Multi Disk)) Down ESCALATION (Connection could not be established (Timeout during establishing - Host: smtp01.uniqa.hr, User: administrator, Password:...)
3. [PRTG Network Monitor] host1 WMI Memory 30 (WMI Memory) Down ESCALATION (Connection could not be established (Timeout during establishing - Host: smtp01.uniqa.hr, User: administrator, Password:...)
I added SNMP sensors for memory, cpu, disk and they are UP at the time the WMI sensors go DOWN. Ping is also up, and the servers function correctly.
It's happening every day, but almost every day, and at is always at the same time.
We checked task scheduler, backup jobs and other automated events that could causing this to happen, event viewer doesen't show any errors or warnings when this happens.
Every help is appreciated
