- MinIO exports Prometheus compatible data by default as an authorized endpoint at `/minio/v2/metrics/cluster`. 

- A working knowledge of AWS S3 API behaviors and corner cases.

## Example Lambda handler

Install the necessary dependencies.
```sh
pip install flask requests
```

Following is an example lambda handler.
```py
from flask import Flask, request, abort, make_response
import requests

app = Flask(__name__)
@app.route('/', methods=['POST'])
def get_webhook():
	if request.method == 'POST':

Bucket events can be published to the following targets:

| Supported Notification Targets    |                             |                                 |

## List of Amazon S3 APIs not supported on MinIO

			ipV4s = append(ipV4s, nip)
		} else {
			nonIPs = append(nonIPs, ip)
		}
	}

	sort.Slice(ipV4s, func(i, j int) bool {
		// This case is needed when all ips in the list
		// have same last octets, Following just ensures that
		// 127.0.0.1 is moved to the end of the list.
		if ipV4s[i].IsLoopback() {
			return false
		}
		if ipV4s[j].IsLoopback() {
			return true
		}

	}{
		// Test case - 1.
		// A Valid v4 presign URL requires the following params to be in the query.
		// "X-Amz-Algorithm", "X-Amz-Credential", "X-Amz-Signature", " X-Amz-Date", "X-Amz-SignedHeaders", "X-Amz-Expires".
		// If these params are missing its expected to get ErrInvalidQueryParams .
		// In the following test case 2 out of 6 query params are missing.

## GNU/Linux

Use the following command to run a standalone MinIO server on Linux hosts running 64-bit Intel/AMD architectures. Replace ``/data`` with the path to the drive or directory in which you want MinIO to store data.

```sh
wget https://dl.min.io/server/minio/release/linux-amd64/minio
chmod +x minio
./minio server /data
```

```
