Check_docker_swarm

This is a plugin that monitors docker swarm quorum i.e. it monitors how many manager nodes of the docker swarm are up and healthy. This plugin returns ‘OK’ when all the managers are healthy and reachable or when we are trying to run the plugin on the worker node. On the other hand it returns ‘WARNING’ when any of the manger node is down, and ‘CRITICAL’ if more than half of the manager nodes are unreachable…
