Monitoring client connections on a cisco C9800-CL with 2.0.0p17 (CRE)

Hi @tosch ,
I’m sorry but you’re right…
I did not verify the version of python used by my check mk server… It was python2…
Now that I made the change, I still have a (null) warning rising when I put the plugin in the directory @andreas-doehler mentioned earlier…
This is what I have :

$ python cisco_wlc.py
Traceback (most recent call last):
  File "cisco_wlc.py", line 43, in <module>
    from .agent_based_api.v1 import (
ModuleNotFoundError: No module named '__main__.agent_based_api'; '__main__' is not a package

Is it better for you or do you need something else to help me, if you can ?
Thanks
