## MinIO Monitoring Guide

MinIO server exposes monitoring data over endpoints. Monitoring tools can pick the data from these endpoints. This document lists the monitoring endpoints and relevant documentation.

### Healthcheck Probe

MinIO server has two healthcheck related un-authenticated endpoints, a liveness probe to indicate if server is responding, cluster probe to check if server can be taken down for maintenance.

- Liveness probe available at `/minio/health/live`
- Cluster probe available at `/minio/health/cluster`

Read more on how to use these endpoints in [MinIO healthcheck guide](https://github.com/minio/minio/blob/master/docs/metrics/healthcheck/README.md).

### Prometheus Probe

MinIO allows reading metrics for the entire cluster from any single node. The cluster wide metrics can be read at
`<Address for MinIO Service>/minio/prometheus/cluster`.

The additional node specific metrics which include go metrics or process metrics are exposed at
`<Address for MinIO Node>/minio/prometheus/node`.

To use this endpoint, setup Prometheus to scrape data from this endpoint. Read more on how to configure and use Prometheus to monitor MinIO server in [How to monitor MinIO server with Prometheus](https://github.com/minio/minio/blob/master/docs/metrics/prometheus/README.md).

**Deprecated metrics monitoring**

- Prometheus' data available at `/minio/prometheus/metrics` is deprecated
