Hey Sergej,
in fact, it’s a bug in the Agent, just CMK handles it different in 2.1 it seems.
Always when it’s happens, the Section is missing all the Information, when you check then again, the information is back.
This is how the Section looks, when the failure appears:
<<<wmi_cpuload:sep(44)>>>
[system_perf]
WMItimeout
[computer_system]
WMItimeout
So, there are Timeouts…
