Question

How can I add Docker integration into my Azure Managed Grafana instance?
Currently, Docker integration to monitor docker containers in any environment is supported by Grafana, but I cannot find the connection in the connection list.

@Jorge Garcia Dominguez You will need to use Prometheus as there is no direct connection provided.

Step 1: Set Up Docker Monitoring with Prometheus

First, you need to set up Docker monitoring using Prometheus, which will collect the metrics from Docker containers.

1. Install Prometheus: You can run Prometheus in a Docker container. Create a prometheus.yml configuration file:

      global:
        scrape_interval: 15s
      scrape_configs:
        - job_name: 'docker'
          static_configs:
            - targets: ['localhost:9323']
   

2. Run Prometheus Container:

      docker run -d --name=prometheus -p 9090:9090 -v $(pwd)/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus
   

3. Install cAdvisor: cAdvisor collects container metrics and exposes them to Prometheus.

      docker run \
        --volume=/:/rootfs:ro \
        --volume=/var/run:/var/run:ro \
        --volume=/sys:/sys:ro \
        --volume=/var/lib/docker/:/var/lib/docker:ro \
        --publish=9323:9323 \
        --detach=true \
        --name=cadvisor \
        google/cadvisor:latest
      
   

Step 2: Configure Azure Managed Grafana to Use Prometheus

Now, you need to configure your Azure Managed Grafana to use Prometheus as a data source.

1. Log in to Azure Managed Grafana: Open your Azure Managed Grafana instance.
2. Add Prometheus Data Source:
   • Navigate to Configuration > Data Sources.
   • Click on Add data source.
   • Select Prometheus from the list.
   • Configure the Prometheus URL. If Prometheus is running locally, the URL will be http://<your-prometheus-host>:9090.
   • Click Save & Test to ensure the connection is working.

Step 3: Import Docker Monitoring Dashboard

Grafana provides pre-built dashboards for Docker monitoring.

1. Import Dashboard:
   • In your Azure Managed Grafana, go to Create > Import.
   • You can find popular Docker monitoring dashboards on Grafana Dashboards. For example, dashboard ID 893 is a common Docker monitoring dashboard.
   • Enter the dashboard ID and click Load.
   • Select the Prometheus data source you configured earlier.
   • Click Import.

Step 4: Visualize Docker Metrics

Once the dashboard is imported, you should start seeing Docker metrics visualized in Grafana. The dashboard will display various metrics such as CPU usage, memory usage, network I/O, and more for your Docker containers.
