# MinIO Healthcheck

MinIO server exposes three un-authenticated, healthcheck endpoints liveness probe and a cluster probe at `/minio/health/live` and `/minio/health/cluster` respectively.

## Liveness probe

This probe always responds with '200 OK'. Only fails if 'etcd' is configured and unreachable. When liveness probe fails, Kubernetes like platforms restart the container.

```
livenessProbe:
  httpGet:
    path: /minio/health/live
    port: 9000

		c = n
	})
	f(s, true)
	if c != 2 {
		panic("bad liveness")
	}
}

func fFalse() {
	var s StkObj
	s.h = new(HeapObj)
	c = -1
	n = 0
	runtime.SetFinalizer(s.h, func(h *HeapObj) {
		// Remember at what phase the heap object was collected.
		c = n
	})
	f(s, false)
	if c != 0 {
		panic("bad liveness")
	}
}

func main() {
	fTrue()
	fFalse()

## 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`

	healthCheckClusterPath     = "/cluster"
	healthCheckClusterReadPath = "/cluster/read"
	healthCheckPathPrefix      = minioReservedBucketPath + healthCheckPath
)

// registerHealthCheckRouter - add handler functions for liveness and readiness routes.
func registerHealthCheckRouter(router *mux.Router) {
	// Healthcheck router
	healthRouter := router.PathPrefix(healthCheckPathPrefix).Subrouter()

	// Cluster check handler to verify cluster is active
