Nagios Support Forum

Hi,

We need help in configuring docker container using check_docker.py (https://exchange.nagios.org/directory/P ... er/details).

Can anyone help in configuring the plugin with example, as we are not able to do so.

Thanks,

We'll certainly assist but keep in mind that at some point you may need to contact the plugins' author for support if it pertains to coding or the like. Reason being, these plugins are not maintained nor were they written by Nagios.
Now with that disclaimer out of the way, at what specific step are you having problems?
What, if any error messages are you seeing?
If you have tried to test the plugin via command line, what were the results?
If applicable, please post text or screenshots relevant to the above questions.

Can you tell me with example how we can pass the argument.

Thanks

It looks as though the connection was refused. Since we didn't develop this plugin, it's hard to offer specific insights into it.

Are you certain the machine you're running the check from is using Python 3? Can you share the outputs of:
