Monitoring Docker Container

README.md

General

Do you want to monitor your Docker Contianer on your VM/Server? You can use this method.

Prerequisites

• Prometheus
• Grafana
• Docker

Create daemon.json

• Create daemon.json

touch /etc/docker/daemon.json
nano /etc/docker/daemon.json

• Fill with this

{
        "metrics-addr" : "0.0.0.0:9323",
        "experimental" : true
}

Fill Prometheus YAML

nano /etc/prometheus/prometheus.yml

  - job_name: 'docker'
    scrape_interval: 5s
    metrics_path: /metrics
    static_configs:
      - targets: ['XXX.XXX.XXX.XXX:9323']

Create Grafana Dashboard

You can use docker.json like the template below.

docker.json
