        ============
        check_docker
        ============
        
        Nagios/NRPE compatible plugins for checking docker based services. Currently there are two nagios checks
        
        -  `check_docker` which checks docker container health
        -  `check_swarm` which checks health of swarm nodes and services
        
        With check_docker can use it to check and alert on
        
        -  memory consumption in absolute units (bytes, kb, mb, gb) and as a percentage (0-100%)
           of the container limit.
        -  CPU usages as a percentage (0-100%) of container limit.
        -  automatic restarts performed by the docker daemon
        -  container status, i.e. is it running?
        -  container health checks are passing?
        -  uptime, i.e. is it able to stay running for a long enough time?
        -  the presence of a container or containers matching specified names
        -  image version, does the running image match that in the remote registry?
        
        With check_swarm you can alert
        
        -  if a node is not joined to a docker swarm
        -  if a service is running in a swarm
        
        These checks can communicate with a local docker daemon socket file (default) or with local
        or remote docker daemons using secure and non-secure TCP connections.
        
        These plugins require python 3. It is tested on 3.3 and greater but may work on older
        versions of 3.

          --present             Modifies --containers so that each RegEx must match at

          --cpu WARN:CRIT       Check cpu usage percentage taking into account any

        Gotchas:
        
        -  When using check_docker with older versions of docker (I have seen 1.4 and 1.5) –status only supports ‘running’, ‘restarting’, and ‘paused’.
        -  When using check_docker, if no container is specified, all containers are checked. Some containers may return critcal status if the selected check(s) require a running container.
