Overview

Integration that allows to:

• Visualize and monitor metrics collected with GitLab Runners through Prometheus
• Validate that the GitLab Runner can connect to GitLab

For more information about the GitLab Runner and its integration with Prometheus, see the GitLab Runner documentation.

Setup

Follow the instructions below to install and configure this check for an Agent running on a host. For containerized environments, see the Autodiscovery Integration Templates for guidance on applying these instructions.

Installation

The GitLab Runner check is included in the Datadog Agent package, so you don’t need to install anything else on your GitLab servers.

Configuration

Edit the gitlab_runner.d/conf.yaml file, in the conf.d/ folder at the root of your Agent’s configuration directory, to point to the Runner’s Prometheus metrics endpoint and to the GitLab master to have a service check. See the sample gitlab_runner.d/conf.yaml for all available configuration options.

The allowed_metrics item in the init_config section allows you to specify the metrics that should be extracted. Some metrics should be reported as rate, for example: ci_runner_errors.

Validation

Run the Agent’s status subcommand and look for gitlab_runner under the Checks section.

Data Collected

Metrics

Log collection

1. In your gitlab_runner configuration file, change the log format to json (Available for GitLab Runner versions >=11.4.0 ):

   log_format = "json"
   

2. Collecting logs is disabled by default in the Datadog Agent, you need to enable it in datadog.yaml:

   logs_enabled: true
   

3. Add the dd-agent user to the systemd-journal group by running:

   usermod -a -G systemd-journal dd-agent
   

4. Add this configuration block to your gitlab_runner.d/conf.yaml file to start collecting your GitLab Runner Logs:

   logs:
     - type: journald
       source: gitlab-runner
   

   See the sample gitlab_runner.d/conf.yaml for all available configuration options.

5. Restart the Agent.

Events

The GitLab Runner check does not include any events.

Service Checks

The GitLab Runner check provides a service check to confirm that the Runner can talk to the GitLab master and another one to ensure that the local Prometheus endpoint is available.
