Lifecycle transition functionality provided in [bucket lifecycle guide](https://github.com/minio/minio/master/docs/bucket/lifecycle/README.md) allows tiering of content from MinIO object store to public clouds or other MinIO clusters.

Bucket metrics can be viewed in the Grafana dashboard using [json file here](https://raw.githubusercontent.com/minio/minio/master/docs/metrics/prometheus/grafana/bucket/minio-bucket.json)

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

This document explains how to setup Prometheus and configure it to scrape data from MinIO servers.

## Prerequisites

- Install MinIO Distributed Server using one of the guides below.
  - [Deployment based on Kubernetes](https://docs.min.io/community/minio-object-store/operations/deployments/kubernetes.html)
  - [Deployment based on MinIO Helm Chart](https://github.com/helm/charts/tree/master/stable/minio)

## **3. Configure Hadoop, Spark, Hive to use MinIO**

spec:
  jobName: {{ template "minio.fullname" . }}
  {{- if .Values.tls.enabled }}
  tlsConfig:
    ca:
      secret:
        name: {{ .Values.tls.certSecret }}
        key: {{ .Values.tls.publicCrt }}
    serverName: {{ template "minio.fullname" . }}
  {{- end }}
  prober:
    url: {{ template "minio.fullname" . }}.{{ .Release.Namespace }}:{{ .Values.service.port }}
    path: /minio/v2/metrics/cluster

- Cluster probe available at `/minio/health/cluster`

Read more on how to use these endpoints in [MinIO healthcheck guide](https://github.com/minio/minio/blob/master/docs/metrics/healthcheck/README.md).

### 1.2 Host Multiple Tenants on Multiple Drives (Erasure Code)

Use the following commands to host 3 tenants on multiple drives:

```sh
minio server --address :9001 /disk{1...4}/data/tenant1
minio server --address :9002 /disk{1...4}/data/tenant2
minio server --address :9003 /disk{1...4}/data/tenant3
```
