Hello!
On some of our Terminalservers we experience some client timeouts after half a day of operations. In the check_mk.log on the client i see where the timeout is coming from.
The WMI Timout is already set to 10s, but i guess that counts for every single WMI call that the client is doing and not for all WMI calls together. Overall Clienttimeout is set to 60s. The problem is fixable with a reboot from the PVS image.
WMI in general looks operational on that server. Is there a way i can blacklist some performance counters from beeing called over WMI?
We have such issues from time to time. In rare cases we couldn’t fix. In general WMI is good but the implementation is disappointing. Even that Microsoft knows about the issues since decades they do nothing.
As far as I know you can only disable sections in the agent. You may can limit with access rights on WMI side but checkmk will complain if not all metrics sent for a specific section.
