Metrics

Metrics provide insight about the operational health of monitored systems. Use metrics to learn more about your systems and applications in a given time range.

Metrics are structured as time series data, and are:

• Indexed by timestamp
• Continuously expanding as additional data is gathered
• Usually aggregated, downsampled, and queried by range
• Have write-intensive requirements

Configure metrics

Configure metrics to enable them for a project.

Prerequisites:

You must have at least the Maintainer role for the project.

1. Create an access token:

   1. On the left sidebar, select Search or go to and find your project.
   2. Select Settings > Access tokens.
   3. Create an access token with the api scope and Developer role or greater. Save the access token value for later.

2. To configure your application to send GitLab metrics, set the following environment variables:

   OTEL_EXPORTER = "otlphttp"
   OTEL_EXPORTER_OTLP_ENDPOINT = "https://gitlab.example.com/api/v4/projects/<gitlab-project-id>/observability/"
   OTEL_EXPORTER_OTLP_HEADERS = "PRIVATE-TOKEN=<gitlab-access-token>"

   Use the following values:

   • gitlab.example.com - The hostname for your GitLab Self-Managed instance, or gitlab.com
   • gitlab-project-id - The project ID
   • gitlab-access-token - The access token you created

Metrics are configured for your project. When you run your application, the OpenTelemetry exporter sends metrics to GitLab.

View metrics

You can view the metrics for a given project:

1. On the left sidebar, select Search or go to and find your project.
2. Select Monitor > Metrics.

A list of metrics is displayed. Select a metric to view its details.

Each metric contains one or more attributes. You can filter metrics by attribute with the search bar.

Metric details

Metrics are displayed as either a sum, a gauge, or a histogram. The metric details page displays a chart depending on the type of metric.

On the metric details page, you can also view metrics for a specific time range, and aggregate metrics by attribute:

To make data lookups fast, depending on what time period you filter by, GitLab automatically chooses the proper aggregation. For example, if you search for more than seven days of data, the API returns only daily aggregates.

Aggregations by search period

The following table shows what type of aggregation is used for each search period:

Metrics ingestion limits

Metrics ingest a maximum of 102,400 bytes per minute. When the limit is exceeded, a 429 Too Many Requests response is returned.

To request a limit increase to 1,048,576 bytes per minute, contact GitLab support.

Data retention

GitLab has a retention limit of 30 days for all ingested metrics.

Create an issue for a metric

You can create an issue to track any action taken to resolve or investigate a metric. To create an issue for a metric:

1. On the left sidebar, select Search or go to and find your project.
2. Select Monitor > Metrics.
3. From the list of metrics, select a metric.
4. Select Create issue.

The issue is created in the selected project and pre-filled with information from the metric. You can edit the issue title and description.

View issues related to a metric

1. On the left sidebar, select Search or go to and find your project.
2. Select Monitor > Metrics.
3. From the list of metrics, select a metric.
4. Scroll to Related issues.
5. Optional. To view the issue details, select an issue.
