Docker

Before creating a new Docker Monitor, the following prerequisites have to be fulfilled.

Docker and Docker Container metrics are collected via their REST API. So, Docker's REST API should be enabled to add a Docker Monitor.

To enable remote API:

1. Open etc\default\docker file

2. Add the below option

DOCKER OPTS='-H tcp://0.0.0.0:4243-H=unix:///var/run/docker.sock'

3. Save the file.

4. Restart Docker.

Once the prerequisites are fulfilled, follow the steps given below to create a new Docker monitor:

1. Click on New Monitor link.

2. Select Docker under Virtualization category.

3. Specify the Display Name of the Docker Monitor.

4. Enter the host name of the server where Docker is running.

5. Enter the Docker socket port to access REST API; default port used is 4243.

6. If you choose the Use Below Credentials option, then enter the credentials - UserName and Password to access Remote REST API. If you choose the Select from credential list option, then select the respective credential from preconfigured credential list.

7. Choose SSL is enabled, if REST API is to be accessed via SSL port. Default SSL port for Docker REST API is 2376.

8. Specify the Polling Interval in minutes.

9. Choose the Monitor Group with which you want to associate the Docker to, from the combo box (optional). You can choose multiple groups to associate your monitor.

10. Click Add Monitor(s). This discovers the Docker from the network and starts monitoring it.
