Hi lmiltchev,

10.23.201.85 is the docker ip address.

Now the status is showing ok (No values) for CPU, Memory usage and running count isin critical state with 0 running.


Docker Container: CPU Usage: Store-order-svc Ok 7d 13h 2m 9s 1/5 2019-12-10 06:57:02 OK:
Docker Container: Memory Usage: Store-order-svc Ok 4d 13h 32m 40s 1/5 2019-12-10 06:55:40 OK:
Docker Container: Running Count: Store-order-svc Critical 24d 20h 51m 45s 5/5 2019-12-10 06:57:48 CRITICAL: 0 running, 1 not running, containers not running: ['/store-order-svc']

Thanks & Regards,

Try running something like this from the command line on the Nagios XI server: or this You should get a "CRITICAL" state, since your container is not running.

Now the status is showing ok (No values) for CPU, Memory usage and running count isin critical state with 0 running.

I will talk to our developers about this, but I would assume that the state is set to "OK" since the containers are NOT running, and CPU & Memory values cannot be determined. Start your container, then run your CPU & Memory checks. You should get some values back now.

Did this help?

Hi lmiltchev,

I'm not sure why the plugin would show different values from your console. Can you show output for these two commands?

Hi swolf,

Are both versions of check_docker.py the same? Please validate.
Which version are you using?
Does this one work on the non-working system?

Thank you!

Hi Ssax,

Tried this https://support.nagios.com/forum/viewto ... 32#p284532
Still same issue.

Tried comparing version of check_docker.py on two of our nagios instances.

[nagios@lxapxxxxx ~]$ grep VERSION /usr/local/nagios/libexec/check_docker.py
__VERSION__ = "1.1.0"
version = '%s, Version %s. See --help for more info.' % (__PLUGIN_NAME__, __VERSION__)
[nagios@lxapxxxx ~]$ timed out waiting for input: auto-logout


[nagios@lxapxxxx ~]$ grep VERSION /usr/local/nagios/libexec/check_docker.py
__VERSION__ = "1.0.4" version = '%s, Version %s. See --help for more info.' % (__PLUGIN_NAME__, __VERSION__)
[nagios@lxapxxxx ~]$ timed out waiting for input: auto-logout

Thanks

The latest version of the check_docker.py plugin is 1.1.1. You can download it from the "Configuration Wizard: Docker - Step 1" page in Nagios XI. Try using the latest plugin to see if this is going to fix your issue.
