All of these can be accessed via Prometheus dashboard. A sample list of exposed metrics along with their definition is available on our public demo server at

```sh
curl https://play.min.io/minio/v2/metrics/cluster
```

### List of metrics reported Cluster and Bucket level

```

```
mc admin service restart myminio
```

Sample URLs for Keycloak are

`config_url` - `http://localhost:8080/auth/realms/demo/.well-known/openid-configuration`

func parseS3ChunkExtension(buf []byte) ([]byte, []byte) {
	buf = trimTrailingWhitespace(buf)
	semi := bytes.Index(buf, []byte(s3ChunkSignatureStr))
	// Chunk signature not found, return the whole buffer.
	if semi == -1 {
		return buf, nil
	}
	return buf[:semi], parseChunkSignature(buf[semi:])
}

// parseChunkSignature - parse chunk signature.
func parseChunkSignature(chunk []byte) []byte {

	// e.g. Forwarded: for=192.0.2.60;proto=https;by=203.0.113.43
	forwarded = http.CanonicalHeaderKey("Forwarded")
	// Allows for a sub-match of the first value after 'for=' to the next
	// comma, semi-colon or space. The match is case-insensitive.
	forRegex = regexp.MustCompile(`(?i)(?:for=)([^(;|,| )]+)(.*)`)
	// Allows for a sub-match for the first instance of scheme (http|https)

## Quickstart

To easily try out the feature, run the included demo Access Management Plugin program in this directory:

```sh
go run access-manager-plugin.go
```

This program, lets the admin user perform any action and prevents all other users from performing `s3:Put*` operations.
