How come i can see some WMI sensors and not all?




I have a server that I auto-discovered and this WMI test popped up:

Physical Disk: Percent Disk Time

I like that test. I tried to clone it to another server which also has a bunch of working WMI sensors but I get the following error:

80041017: The query was not syntactically valid.

I tried doing an auto discover but that test never appears. Any suggestions?

there is problem in the WMI System on the target. Which is why the sensors are not added, because they would only show errors then, due to the broken WMI on the target. Please try repairing the WMI System on the target.

best regards.
