Metrics Version 3

In metrics version 3, all metrics are available under the following base endpoint:

/minio/metrics/v3

To query metrics of a specific type, append the appropriate path to the base endpoint. Querying the base endpoint returns "404 Not Found."

Metrics are organized into groups at paths relative to the top-level endpoint above.

Metrics are also available using the MinIO Admin Client and the mc admin prometheus metrics command. For more information, see Metrics and Alerts in the MinIO Documentation.

Metrics Request Handling

Each endpoint can be queried as needed via a scrape configuration in Prometheus or a compatible metrics collection tool. You should schedule scrape operations so a prior scrape completes before the next one begins.

For ease of configuration, each (non-empty) parent of the path serves all the metric endpoints at its child paths. For example, to query all system metrics scrape /minio/metrics/v3/system/.

Each metric endpoint may support multiple child endpoints. For example, the /v3/system/ metric has multiple child groups as /v3/system/<child>. Querying the parent endpoint returns metrics for all child groups. Querying a child group returns only metrics for that child.

Per-bucket Metrics

Metrics with a /bucket component in the path return results for each specified bucket in the deployment. These endpoints require providing a list of buckets as a bucket query parameter. The endpoint then returns only metrics for the given buckets, with the bucket name in a bucket label.

For example, to query API metrics for buckets test1 and test2, make a scrape request to /minio/metrics/v3/api/bucket?buckets=test1,test2.

List Available Metrics

Instead of a metrics scrape, you can list the metrics that would be returned by a path by adding a list query parameter. The MinIO server then lists all available metrics that could be returned. Note that during an actual metrics scrape only metrics with available values are returned. Metrics with null values are omitted from the scrape results.

To set the output format, set the request Content-Type to the desired format. Accepted values are application/json for JSON output or text/plain for a Markdown-formatted table. The default is Markdown.

For example, the the following returns a list of all available bucket metrics:

/minio/metrics/v3/api/bucket?list

Metric Categories

At a high level, metrics are grouped into categories as described in the following sections. The path in each of the tables is relative to the top-level endpoint. Note that the standard GoCollector metrics are not shown.
