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,

Using netstat ccommand to be sure that wmi_server is running and listening:
netstat -nlp
tcp 0 0 127.0.0.1:2313 0.0.0.0:* LISTEN 222771/python3.8

Using ps command to see wmi_server processes running too:
ps ax
222771 ? SNs 0:00 /usr/bin/python3.8 /usr/bin/gunicorn -b 127.0.0.1:2313 –pythonpath /usr/aiowmi/contrib/wmic_server –threads 1 wmic_server:app

Testing now with latest check_wmi_plus.pl script and receive ERROR: 500 ….
./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)
