I have been working with Solarwinds support starting on week 2 now so hopefully someone here can shed some light on this issue. I have a bunch of webservers that I am monitoring that are not domain joined. I have created local accounts that are local administrators on all of them so they can report back to Orion with any issues or non issues or just regular monitoring. I have quite a few servers setup this way and they work just fine. I have one server that I have tried WMI and Agent and get the same results. Does anyone have any ideas at all? Here is a screen shot. Thanks!
I have seen similar issues. Rebuilding the Performance monitors on that machine should help.
