Hi Community!

I am facing on testing wsman cpu plugin, I followed the documentation provided, except the part of adding a new dedicated user, because I am testing with Administrator.



Any idea on how to fix UNKNOWN: Could not enumerate instances: SSL connect error

Centos 8 Stream

Centreon 22.04


Thanks in advance.

Is it possible to run the command with --debug flag please so we can get more information about the issue?

after days of search for my own system : https port for WSMAN is 5986 and not 5985 (http).

after that you might have more errors. Here is a command ligne that works :

/usr/lib/centreon/plugins/ --plugin=os::windows::wsman::plugin --mode=services --hostname=server.toto.local --wsman-scheme=https --wsman-port=5986 --wsman-username='' --wsman-password=''  --auto --exclude='' --wsman-auth-method='gssnegotiate' --verbose


I also have to add 2 entries in krb5.conf in [libdefaults] :

default_tgs_enctypes = arcfour-hmac-md5 des-cbc-crc des-cbc-md5
 default_tkt_enctypes = arcfour-hmac-md5 des-cbc-crc des-cbc-md5


Hope it help !


Hello everyone,

I'm updating this feed. Do you have any update regarding this error ? I am using a Debian 11 Centreon + AD account to monitor this same exact server. I have few doubts about the possibility of doing it with a domain account and not a local account.
