*   You can now override the health check parameters for AWS ELBs by specifying annotations on the corresponding service. The new annotations are: `healthy-threshold`, `unhealthy-threshold`, `timeout`, `interval`. The prefix for all annotations is  `service.beta.kubernetes.io/aws-load-balancer-healthcheck-`.

## 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
    scheme: HTTP
  initialDelaySeconds: 120

		return ctx, done, ctx.Err()
	}

	atomic.StoreInt64(&p.health.lastStarted, time.Now().UnixNano())
	p.health.waiting.Add(1)

	ctx = context.WithValue(ctx, healthDiskCtxKey{}, &healthDiskCtxValue{lastSuccess: &p.health.lastSuccess})
	si := p.updateStorageMetrics(s, paths...)
	var once sync.Once
	return ctx, func(sz int64, errp *error) {
		p.health.waiting.Add(-1)
		once.Do(func() {

- During device plugin allocation, resources requested by the pod can only be allocated if the device plugin has registered itself to kubelet AND healthy devices are present on the node to be allocated. If these conditions are not sattsfied, the pod would fail with `UnexpectedAdmissionError` error.

## Prometheus Probe

```sh
mc admin trace --verbose myminio
```

To trace entire HTTP request and also internode communication

```sh
mc admin trace --all --verbose myminio
```
