checkmk 2.1 > [agent] Success, Missing monitoring data for plugins: wmi_cpuload <<WARN>>
the problems seams to be that sometime that windows machine, does not deliver wmi data and since
checkmk version 2.1 the handling of the missing data on the server side is different, so that we get a warning.
It is said that updating the client agent also to version > 2.1 should improve that, but if you need a quick solution
you can take the advise from the checkmk article:
https://forum.checkmk.com/t/update-from-2-0-0p22-to-2-1-missing-monitoring-data-for-plugins-wmi-cpuload/31815/45
on your checkmk server modify the file wmi_cpuload.py:
/omd/versions/default/lib/python3/cmk/base/plugins/agent_based/wmi_cpuload.py
--------------------------------------------------------------------------------
Original
--------------------------------------------------------------------------------
try:
load = wmi_tables["system_perf"].get(0, "ProcessorQueueLength")
timestamp = get_wmi_time(wmi_tables["system_perf"], 0)
computer_system = wmi_tables["computer_system"]
except (KeyError, WMIQueryTimeoutError):
return None
assert load
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------
changed version
--------------------------------------------------------------------------------
try:
load = wmi_tables["system_perf"].get(0, "ProcessorQueueLength")
except (KeyError, WMIQueryTimeoutError):
load = 0.0
try:
timestamp = get_wmi_time(wmi_tables["system_perf"], 0)
except (KeyError, WMIQueryTimeoutError):
timestamp = 0.0
try:
computer_system = wmi_tables["computer_system"]
except (KeyError, WMIQueryTimeoutError):
return None
--------------------------------------------------------------------------------
ps:
- when I tested this I was running CEE 2.1.0.p22
- make sure to make no unindent level errors when editing the file wmi_cpuload.py!
