now I’m launch one wmi_check and don’t run

 ./check_wmi_plus.pl  -H IP -m checkcpu
UNKNOWN - The WMI query had problems. Something is probably wrong with the wmic_server (http://127.0.0.1:2313/wmic)

Have you one idea for this bug?

Best regards.

Have you checked logs of the wmic server itself? Is it even installed? Can you query the host with the wmic server itself?

[palouf34]

I have set up the new wmic system because our monitoring is not working anymore since a windows update, which blocks the integration.

Our wmi monitors had been working for about 8 years.

Please make sure that you have performed the testing on the wmic server as per https://github.com/cesbit/aiowmi/tree/main/contrib/wmic_server#testing-the-server

Also, please run that same testing from the nagios server to the wmic_server

Sorry, I was not clear.
Please provide all the output from a complete run of the plugin which does a WMI check and sends a command to the wmic server, using -d -d.

eg check_wmi_plus.pl -H HOST -u USER -p TOKEN -m checkdrivesize -a . -d -d

[gmourani]

Hello,

It works, the problem was that it was necessary to add in the command line check_wmi_plus.pl the option -u user1 so that it uses the credentials of the user in question. I never put this option because not explain in the guide and on the site. Now and without any modification, adding the -u username option makes it work, thanks.

Regards,

[admin]

This requirement is documented in the –help output of check_wmi_plus.pl

       REQUIRED  OPTIONS  FOR WMIC Server 
These only apply if using the new WMIC Server You must specify username/password/domain (referred to as auth info) in the
       WMIC Server configuration. Check WMI PLus does not hold auth info. It only points to the auth info in the WMIC Server.  You must point to the auth info  us‐
       ing an identifier that matches one in the WMIC Server configuration.

              -u ID  specify the identifier for the auth info that matches the one defined in the WMIC Server

              -p TOKEN
                     specific  the token required to authenticate to the WMIC Server. This is not Windows authentication information. The tokens are defined in the
                     WMIC Server configuration
