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

## Prerequisites

To get started with MinIO, refer [MinIO QuickStart Document](https://min.io/docs/minio/linux/index.html#quickstart-for-linux).
Follow below steps to get started with MinIO monitoring using Prometheus.

### 1. Download Prometheus

### Certificate Directory

Object locking requires locking to be enabled on a bucket at the time of bucket creation refer to `mc mb --with-lock`, object locking enables versioning on the bucket and cannot be disabled.

```bash
helm upgrade -f old_values.yaml my-release minio/minio
```

Default upgrade strategies are specified in the `values.yaml` file. Update these fields if you'd like to use a different strategy.

### Configuration

Refer the [Values file](./values.yaml) for all the possible config fields.

You can specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,

```bash

- MinIO-Operator: Operator offers seamless way to create and update highly available distributed MinIO clusters. Refer [MinIO Operator documentation](https://github.com/minio/minio-operator/blob/master/README.md) for more details.

- Helm Chart: MinIO Helm Chart offers customizable and easy MinIO deployment with a single command. Refer [MinIO Helm Chart documentation](https://github.com/minio/minio/tree/master/helm/minio) for more details.

etcd is a distributed key value store that provides a reliable way to store data across a cluster of machines.

## Get started

### 1. Prerequisites

- Docker 18.03 or above, refer here for [installation](https://docs.docker.com/install/).

### 2. Start etcd

etcd uses [gcr.io/etcd-development/etcd](https://console.cloud.google.com/gcr/images/etcd-development/GLOBAL/etcd) as a primary container registry.

```sh
export MINIO_STORAGE_CLASS_STANDARD=EC:3
export MINIO_STORAGE_CLASS_RRS=EC:2
```

Storage class can also be set via `mc admin config` get/set commands to update the configuration. Refer [storage class](https://github.com/minio/minio/tree/master/docs/config#storage-class) for
more details.

#### Note

### Push to the branch

Push your locally committed changes to the remote origin (your fork)

```
git push origin my-new-feature
```

### Create a Pull Request

Pull requests can be created via GitHub. Refer to [this document](https://help.github.com/articles/creating-a-pull-request/) for detailed steps on how to create a pull request. After a Pull Request gets peer reviewed and approved, it will be merged.

Only the root/admin user can perform an SSE-S3 key rotation using the Admin-API via [mc](https://github.com/minio/mc). For more details about how to perform key management operations using the CLI refer to [mc admin guide](https://github.com/minio/mc/blob/master/docs/minio-admin-complete-guide.md) or run `mc admin kms key`.
