Follow below steps to enable and use AlertManager.

## Deploy and start AlertManager
Install Prometheus AlertManager from https://prometheus.io/download/ and create configuration as below

```yaml
route:
  group_by: ['alertname']

If your lambda target expects an authorization token then you can enable it per function target as follows

```
MINIO_LAMBDA_WEBHOOK_ENABLE_function=on MINIO_LAMBDA_WEBHOOK_ENDPOINT_function=http://localhost:5000 MINIO_LAMBDA_WEBHOOK_AUTH_TOKEN="mytoken" minio server /data &
```

### Lambda Target with mTLS authentication

If your lambda target expects mTLS client you can enable it per function target as follows
```

	EnvRedisQueueDir   = "MINIO_NOTIFY_REDIS_QUEUE_DIR"
	EnvRedisQueueLimit = "MINIO_NOTIFY_REDIS_QUEUE_LIMIT"
)

// RedisArgs - Redis target arguments.
type RedisArgs struct {
	Enable     bool      `json:"enable"`
	Format     string    `json:"format"`

	Password   string    `json:"password"`

	}

	cnt := 0
