# 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

	}

### Kafka Target

Assuming that you already have Apache Kafka configured and running.

```
mc admin config set myminio/ audit_kafka
KEY:
audit_kafka[:name]  send audit logs to kafka endpoints

ARGS:
brokers*         (csv)       comma separated list of Kafka broker addresses
topic            (string)    Kafka topic used for bucket notifications
