# 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. This allows for metrics collection for a MinIO instance across all servers. Thus, metrics collection for instances behind a load balancer can be done without any knowledge of the individual node addresses. The cluster wide metrics can be read at
|
|
`<Address for MinIO Service>/minio/v2/metrics/cluster`.
|
|
|
|
The additional node specific metrics which include additional go metrics or process metrics are exposed at
|
|
`<Address for MinIO Node>/minio/v2/metrics/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
