### Checking cluster health for maintenance

You may query the cluster probe endpoint to check if the node which received the request can be taken down for maintenance, if the server replies back '412 Precondition Failed' this means you will lose HA. '200 OK' means you are okay to proceed.

```
curl http://minio1:9001/minio/health/cluster?maintenance=true
HTTP/1.1 412 Precondition Failed
Accept-Ranges: bytes

### Environment variables

#### MINIO_ETCD_ENDPOINTS

This is comma separated list of etcd servers that you want to use as the MinIO federation back-end. This should
be same across the federated deployment, i.e. all the MinIO instances within a federated deployment should use same
etcd back-end.

#### MINIO_DOMAIN

This is the top level domain name used for the federated setup. This domain name should ideally resolve to a load-balancer

MINIO_NOTIFY_AMQP_COMMENT        (sentence)  optionally add a comment to this setting
```

# 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.

## Replica Modification sync

> NOTE: MinIO runs console on random port by default, if you wish to choose a specific port use `--console-address` to pick a specific interface and port.

### Things to consider

		# Transform all text in the original object to uppercase
		# You can replace it with your custom code based on your use case
		transformed_object = original_object.upper()

		# Write object back to S3 Object Lambda
		# response sends the transformed data
		# back to MinIO and then to the user
		resp = make_response(transformed_object, 200)
		resp.headers['x-amz-request-route'] = request_route
		resp.headers['x-amz-request-token'] = request_token
