Zabbix automatic discovery and monitoring Docker containers

At first, you need to install jq utility to generate JSON in bash. You are SA, you know how to do it.

JSON you want to receive from agent looks like:


Create new custom config on target host /etc/zabbix/zabbix_agentd.d/docker.conf [download]

UserParameter=docker.running[*],docker ps -a -f name="$1" -f status=running -q
UserParameter=docker.containers_running,docker ps -f status=running -q|wc -l
UserParameter=docker.containers_all,docker ps -a -q|wc -l
UserParameter=docker.discovery,echo -n "$(docker ps -a -q --format='{{.Names}}')"|/usr/bin/jq -R -s -c '{data:  split("\n") | map({"{#CONTAINER}": (.)}) }'

You can import my xml with template, or create your own below.

Sample graph in my template

Now create new template “Template Docker containers” with Application “Docker” and discovery rule “Docker containers discovery”. Just like on screenshot below.

Now create templates for Item and Trigger

At last step assign newly created template to your monitored host.

Great! Now you can see statuses and receive alerts.

    в правиле обнаружений ошибка – Value should be a JSON object.

  2. 21h says:

    а точно именно json отдается?

  3. Axet says:

    something is wrong

    Invalid discovery rule value: cannot parse as a valid JSON object: invalid object format, expected opening character ‘{‘ or ‘[‘ at: ‘3proxy
    registry |/usr/bin/jq -R -s -c {data: split(”
    “) | map({“{#CONTAINER}”: (.)}) }’

  4. 21h says:

    my config
    may be something wrong with your containers list, please paste it to

  5. S1str says:

    Ошибка скорее всего из-за того что нет прав на запуск команды

  6. Влад says:

    Почему не срабатывает тригер?
