Docker monitoring is performed via the OS agent in a container. Deploy the agent on each monitored Docker host.


Prerequisites

  • Opened TCP communication between each Docker server and XorMon server on port 8162.
    Connections are initiated from Docker server side.

Docker agent installation

  • Pull the image 
    docker pull xorux/lpar2rrd-docker-agent
  • Run the docker agent 
    docker run --init -d --hostname $(hostname) --name lpar2rrd-docker-agent -v /var/run/docker.sock:/var/run/docker.sock:ro --env XORMON=<XorMon-NG_hostname/IP> xorux/lpar2rrd-docker-agent
