Metrics version 3 (v3) provides additional metrics and metric types for more targeted scraping.

MinIO publishes metrics using the Prometheus Data Model <concepts/data_model/>. You can use any scraping tool to pull metrics data from MinIO for further analysis and alerting.

You can also access metrics using mc admin prometheus metrics and the metric type for the desired category. For more information, see the MinIO Admin Client reference <mc admin prometheus metrics>.

The MinIO Operator supports deploying a per-tenant Prometheus instance configured to support metrics and visualization.

If you deploy the Tenant with this feature disabled but still want the historical metric views, you can instead configure an external Prometheus service to scrape the Tenant metrics. Once configured, you can update the Tenant to query that Prometheus service to retrieve metric data:

linux or container or macos or windows

To enable historical data visualization in MinIO Console, set the following environment variables on each node in the MinIO deployment:

• Set MINIO_PROMETHEUS_URL to the URL of the Prometheus service
• Set MINIO_PROMETHEUS_JOB_ID to the unique job ID assigned to the collected metrics
