Metrics and Alerts

MinIO publishes cluster and node metrics using the Prometheus Data Model. You can use any scraping tool to pull metrics data from MinIO for further analysis and alerting.

MinIO provides scraping endpoints for the following metric groups:

You can scrape cluster-level metrics using the following URL endpoint:

http://HOSTNAME:PORT/minio/v2/metrics/cluster

Replace HOSTNAME:PORT with the FQDN and port of the MinIO deployment. For deployments with a load balancer managing connections between MinIO nodes, specify the address of the load balancer.

Changed in version RELEASE.2023-08-31T15-31-16Z.

You can scrape bucket-level metrics using the following URL endpoint:

http://HOSTNAME:PORT/minio/v2/metrics/bucket

Replace HOSTNAME:PORT with the FQDN and port of the MinIO deployment. For deployments with a load balancer managing connections between MinIO nodes, specify the address of the load balancer.

MinIO by default requires authentication for scraping the metrics endpoints. Use the mc admin prometheus generate command to generate the necessary bearer tokens. You can alternatively disable metrics endpoint authentication by setting MINIO_PROMETHEUS_AUTH_TYPE to public.

MinIO Console Metrics Dashboard

The MinIO Console provides a point-in-time metrics dashboard by default:

MinIO Console with Point-In-Time Metrics

The Console also supports displaying time-series and historical data by querying a Prometheus service configured to scrape data from the MinIO deployment. Specifically, the MinIO Console uses Prometheus query API to retrieve stored metrics data and display the following visualizations:

  • Usage - provides historical and on-demand visualization of overall usage and status

  • Traffic - provides historical and on-demand visualization of network traffic

  • Resources - provides historical and on-demand visualization of resources (compute and storage)

  • Info - provides point-in-time status of the deployment

MinIO Console displaying Prometheus-backed Monitoring Data

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:

MinIO Grafana Dashboard

MinIO also publishes two Grafana Dashboards for visualizing collected metrics. For more complete documentation on configuring a Prometheus-compatible data source for Grafana, see the Prometheus documentation on Grafana Support.

Available Metrics

MinIO publishes a number of metrics at the cluster, node, or bucket levels. Each metric includes a label for the MinIO server which generated that metric.

Changed in version MinIO: RELEASE.2023-07-21T21-12-44Z

Bucket metrics have moved to use their own, separate endpoint.

Cluster Metrics

MinIO collects the following metrics at the cluster level. Metrics may include one or more labels, such as the server that calculated that metric.

These metrics can be obtained from any MinIO server once per collection by using the following URL:

https://HOSTNAME:PORT/minio/v2/metrics/cluster

Replace HOSTNAME:PORT with the hostname of your MinIO deployment. For deployments behind a load balancer, use the load balancer hostname instead of a single node hostname.
