Zabbix automatic discovery and monitoring Docker containers

№ 9617 В разделе "Администрирование" от December 2nd, 2018,

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:

{"data":[{"{#CONTAINER}":"git"},{"{#CONTAINER}":"ark_storage_api"},{"{#CONTAINER}":"telegram-microblog-poster"},{"{#CONTAINER}":"telegram-microblog-site"},{"{#CONTAINER}":"mqtt-zabbix-agent"},{"{#CONTAINER}":"sbnc"},{"{#CONTAINER}":"mqtt-bus"},{"{#CONTAINER}":"zabbix-server"},{"{#CONTAINER}":"telegram-post-bot"},{"{#CONTAINER}":"mat-generator"},{"{#CONTAINER}":"ark-log-server"},{"{#CONTAINER}":"zabbix-panel"},{"{#CONTAINER}":"splash"},{"{#CONTAINER}":"mariadb"},{"{#CONTAINER}":"postgres"}]}

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

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.

    а точно именно json отдается?

Хорошая шпаргалка по пластикам для печати drive.google.com/file/d/1NKB3- В принципе, данные практически сходятся с моими blindage.org/?p=10199
