Sensor for Docker Container monitoring

Good morning,

today I wrote a script to monitor the services on a docker host.

You'll get a warning if a container is dead which should be running.

Just move the script to /var/prtg/scripts and create a new sensor "SSH Scripts"

Dont forget to execute chmod +x !

#!/bin/sh

#Variables

hostname="`cat /etc/hostname`"

#MAIN
deadcontainer="`docker service ls --format {{.Name}}:{{.Replicas}} | grep '0/1' | cut -d':' -f1`"
if [ "$deadcontainer" == "" ]; then
    echo "0:1:All container are running"
    exit 0
else
    for i in $deadcontainer; do
        echo "1:0:$deadcontainer is not running"
        exit 1
    done
fi

Have fun!
