Hi Andreas,
yes sorry my description was misleading.
First we had all sections enabled on all servers. During this time the stales for disk IO, dotnet or webservice appeared random.
After some further investigation we disabled “Execute legacy monitoring plugins, MS Exchange counters (various), Web Services, .Net/CLR Memory, Hardware Sensors via OpenHardwareMonitor, Skype for Business” globally and enabled them only there where it is needed.
After this change the dotnet and webservice stale checks are only appearing where they are configured. Stale Disk IO can appear on any machine, because its enabled everywhere.
Yes the stale status only appears for one check intervall. on the next check interval it disappers but is stale on an other machine. We have ~50 vm in the current config but are about to go up to ~300. So i am afraid it will get worse.
