Interval Delay WMI on PRTG standalone probe health is 400%



We've not added many sensors recently, but our PRTG monitoring has about 700 active sensors. We are struggling to monitor anything other than ping alerts, because WMI-related sensors all appear to be going offline and the probe health indicates WMI queries are significantly delayed.

Thank you for your post.

In order to investigate this, log files from your PRTG core server are needed. Because of this I would suggest that you open a support ticket. You can do this in the PRTG web interface by going to Setup>Contact Support, and make sure that you send a support bundle as well.

If your PRTG does not have access to the internet, you can also open a ticket by writing a email to [email protected].

Kind regards,
Sasa Ignjatovic, Tech Support Team
