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.
Interval Delay WMI on PRTG standalone probe health is 400%

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 support@paessler.com.
Kind regards,
