(non-empty) parent of the path serves all metric endpoints that are at descendant paths. For example, to query all system metrics one needs to only scrape `/minio/metrics/v3/system/`.

Some metrics are bucket specific. These will have a `/bucket` component in their path. As the number of buckets can be large, the metrics scrape operation needs to be provided with a specific list of buckets via the `bucket` query parameter. Only metrics for the given buckets will be returned (with the bucket label set)....

Alerting with prometheus is two step process. First we setup alerts in Prometheus server and then we need to send alerts to the AlertManager.
