Hello, I would like your help, I have 2 docker containers that I would like to monitor with Centreon, the truth is that I have no idea how to start or carry out this work, if it is possible for the console to be seen in case the container is down or up

Hello @cristianandres9 

For Docker you have 3 possibilities dedicated to that.

Docker | Centreon Documentation

cAdvisor API | Centreon Documentation

cAdvisor | Centreon Documentation

With the first you have a mode who would be a solution for you, documentation is not updated.

So you could see here the differents mode for Docker :

https://github.com/centreon/centreon-plugins/blob/e40d869bf4a584d1b5228b3b31686ee49a80606a/cloud/docker/restapi/plugin.pm#L33

With cAdvisor, you have the API :

https://github.com/centreon/centreon-plugins/blob/e40d869bf4a584d1b5228b3b31686ee49a80606a/cloud/cadvisor/restapi/plugin.pm#L33

And By Prometheus cAdvisor : 

https://github.com/centreon/centreon-plugins/blob/e40d869bf4a584d1b5228b3b31686ee49a80606a/cloud/prometheus/exporters/cadvisor/plugin.pm#L33

hi and thanks @gespada clone the git repository but I'm stuck in tests I'm doing the perl command centreon_plugins.pl --plugin=cloud::docker::restapi::plugin --mode=node-status --help why I think it's the one I need to see the status of the container but I don't know how to complement it
this is the docker I want to test:

CONTAINER ID   IMAGE                                   COMMAND                  CREATED         STATUS          PORTS                                            NAMES
e39fe4f9a030 docker.elastic.co/kibana/kibana:7.3.1 "/usr/local/bin/dumb…" 3 months ago Up 3 months 0.0.0.0:5601->5601/tcp kibana


I appreciate any guide

Hello,

Have you check the differents tips here (first to apply best security practice ) : https://thewatch.centreon.com/product-how-to-21/best-practices-how-to-secure-the-monitoring-of-your-docker-container-266

And here (a deployment in French) : https://www.sugarbug.fr/framboise/clusterhat_pi/monitoring/

According your Docker version, API is : https://docs.docker.com/engine/api/#api-version-matrix

Enable the Rest API is mandatory, in order to monitor Docker with centreon-plugins :  ://docs.centreon.com/pp/integrations/plugin-packs/procedures/applications-docker-restapi/#prerequisites

If you have activated Docker Rest API and you have an retour, please post a detail of your command and error message.

To troubleshoot, you could add --debug option at the command.
