Full Description

Dockbix Agent XXL - Zabbix Agent with Docker monitoring

dockbix-agent-xxl-limited is a 2nd generation of successful (500k+ pulls) zabbix-agent-xxl-limited Docker image - it's a standard Zabbix agent with Docker/host/systemd/socket/stress metrics support, which can be used with any Zabbix server. Tested on CoreOS, RHEL, CentOS, Ubuntu, Debian, Fedora, Boot2docker, Photon OS.

If you like or use this project, please provide feedback to author - Star it ★ or submit feedback form.

Overview of Monitoring Artist (dockerized) monitoring ecosystem:

Start Dockbix agent container and monitor all Docker containers on your host. Module Zabbix Docker monitoring is used - all docker module container metrics are available except docker.xnet. Import/assign Dockbix Agent XXL templates + then just start Dockbix agent container:

docker run \
  --name=dockbix-agent-xxl \
  --net=host \
  --privileged \
  -v /:/rootfs \
  -v /var/run:/var/run \
  --restart unless-stopped \
  -e "ZA_ServerActive=<ZABBIX SERVER IP/DNS NAME>" \
  -d monitoringartist/dockbix-agent-xxl-limited:latest

If Docker user namespaces are enabled, then you need also --userns=host.

docker run --rm -t monitoringartist/dockbix-agent-xxl-limited version

Public limited vs private paid image

Public limited Docker image monitoringartist/dockbix-agent-xxl-limited:latest
has almost the same functionality as private paid Docker image
monitoringartist/dockbix-agent-xxl:latest. However, limited version:

  • doesn't support custom UserParameter(s)
  • doesn't support command execution in the container; for example, you can't
    use[] item
  • doesn't support any shell access in the container; for example, you can't
    use docker exec -ti dockbix-agent-xxl bash
  • collects Google Analytics statistics (Docker version, kernel version, execution driver,
    Dockbix agent container start-up errors), which are used for improvements;
    statistics may also be used for public presentations

General limitations:

  • Dockbix agent container doesn't support docker stop/start container commands
  • Dockbix agent container doesn't support docker.xnet container metrics
  • host metric support is not complete; CPU and net host metrics are available, filesystem metrics with /rootfs prefix, process (proc.*) are not available due to cgroup limitation

Environment configuration variables

You can use almost any agent config parameter, just add prefix ZA_. If you don't specify a custom setting variable, then default Zabbix agent setting will be used. For example, you want to use StartAgents=10, just add environment variable -e "ZA_StartAgents=10".


docker run \
  --name=dockbix-agent-xxl \
  --net=host \
  --privileged \
  -v /:/rootfs \
  -v /var/run:/var/run \
  --restart unless-stopped \
  -e "ZA_ServerActive=<ZABBIX SERVER IP/DNS NAME>" \
  -e "ZA_StartAgents=10" \
  -e "ZA_Timeout=30" \
  -d monitoringartist/dockbix-agent-xxl-limited:latest

You can't override some parameters: AllowRoot, LoadModulePath, LoadModule, LogType, because Docker monitoring module is used. Also, Zabbix agent configuration from the config file is not supported.

Zabbix templates

Example of Zabbix templates, which can be used with Dockbix agent:

Public Dockbix Agent XXL

Public Dockbix agent XXL is available on the address It's available for anyone as a public part of the monitoringartist playground. Just create a new host in your Zabbix server with this configuration:

How it works

No classic rpm/deb package installation or Zabbix module compilation. Just start the dockbix-agent-xxl container and Docker container metrics will be collected from the Docker daemon API or cgroups.

How to monitor dockerized apps

Ideas about monitoring of dockerized apps:

  • health endpoint: publish app health as a HTTP endpoint, which can be used for monitoring (item keys:,
  • monitor them as a service: use standard Zabbix TCP/HTTP check (item keys: net.tcp.port, net.tcp.service, net.tcp.service.perf)
  • monitor them as a process: use standard Zabbix process check (item key: proc.num)

First try to troubleshoot problems yourself. Increase debug level -e 'ZA_DebugLevel=5' and check the container logs docker logs dockbix-agent-xxl. Try to obtain raw values from the agent, for example:

# docker exec -ti dockbix-agent-xxl zabbix_get -s -k docker.mem[/dockbix-agent-xxl,rss]

Other options:

All reported issues, which are not real issues, but requests for support will be closed with reference to this README section.
