Processor Queue UNKN - Missing information from agent: 'system_perf'

Open the Windows agent's log file and see if you find this:

2021-08-03 17:15:35.063 [Err  ] Timeout [3] seconds broken  when query WMI
...
...
...
2021-08-03 15:02:44.435 [Warn ] Object 'Win32_PerfRawData_PerfOS_System' in 4ms sends NO DATA
2021-08-03 15:02:44.436 [Warn ] Sub Section 'system_perf' has no data to provide, status = [2]

Which counter does wmi_cpuload use? 

You will find the source code of the Windows Agent in our GitHub. There you will find all the System and Performance counters. For wmi_cpuload, we need the following counters:

root@mylinuxhost:/# grep -A5 "CPULOAD" /home/anastasiosmylinuxuser/git/check_mk/agents/wnx/src/engine/providers/wmi.cpp
// WMI CPULOAD group
{"system_perf", //
{kWmiPathStd, L"Win32_PerfRawData_PerfOS_System"}},

{"computer_system", //
{kWmiPathStd, L"Win32_ComputerSystem"}},

Now you can run both commands. What's the output? Do you see all the data like described here: Microsoft win32 Documentation

Get-WmiObject -class Win32_PerfRawData_PerfOS_System -computername  WIN-MOP95J96UQA -namespace   root\cimv2 |Format-List *

Get-WmiObject -class Win32_ComputerSystem | Format-List *

How long does the query run? You can use the measurement command for this:

https://docs.microsoft.com/de-de/windows/win32/cimwin32prov/win32-computersystem

Measure-Command {Get-WmiObject -class Win32_PerfRawData_PerfOS_System -computername WIN-MOP95J96UQA -namespace root\cimv2 |Format-List *}
Measure-Command {Get-WmiObject -class Win32_ComputerSystem | Format-List *}

Possible solutions

• Increase the wmi timeout as described here: How-to increase WMI timeout
  
  
• Reboot the system
  
  

• WMI Database is broken → Use the WMI Explorer for further debugging
  
  You can try these commands, but be careful
  
  Rebuilding WMI repository
