- 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

![spark-config](https://github.com/minio/minio/blob/master/docs/bigdata/images/image9.png?raw=true "spark defaults")

Add the following optimal entries for _spark-defaults.conf_ to configure Spark with **MinIO**.

```
spark.hadoop.fs.s3a.access.key minio
spark.hadoop.fs.s3a.secret.key minio123
spark.hadoop.fs.s3a.path.style.access true
spark.hadoop.fs.s3a.block.size 512M

### 1. Prerequisites

- Install mc - [MinIO Client Quickstart Guide](https://docs.min.io/community/minio-object-store/reference/minio-mc.html#quickstart)
- Install MinIO - [MinIO Quickstart Guide](https://docs.min.io/community/minio-object-store/operations/deployments/baremetal-deploy-minio-on-redhat-linux.html)
- Configure etcd - [Etcd V3 Quickstart Guide](https://github.com/minio/minio/blob/master/docs/sts/etcd.md)

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
```

### Setup your MinIO GitHub Repository

Fork [MinIO upstream](https://github.com/minio/minio/fork) source repository to your own personal repository. Copy the URL of your MinIO fork (you will need it for the `git clone` command below).

```sh
git clone https://github.com/minio/minio
cd minio
go install -v
ls $(go env GOPATH)/bin/minio
```

### Set up git remote as ``upstream``

```sh
