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

	f.pretty(msg, args...)
}

var (
	logTag      = "ERROR"
	logBanner   = color.BgRed(color.FgWhite(color.Bold(logTag))) + " "
	emptyBanner = color.BgRed(strings.Repeat(" ", len(logTag))) + " "
	bannerWidth = len(logTag) + 1
)

func (f fatalMsg) pretty(msg string, args ...interface{}) {
	// Build the passed error message
	errMsg := fmt.Sprintf(msg, args...)

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.

	stats, err := readStat(statsFile)
	if err != nil {
		return IOStats{}, err
	}
	if len(stats) < 11 {
		return IOStats{}, fmt.Errorf("found invalid format while reading %v", statsFile)
	}
	// refer https://www.kernel.org/doc/Documentation/block/stat.txt
	iostats = IOStats{
		ReadIOs:      stats[0],
		ReadMerges:   stats[1],
		ReadSectors:  stats[2],
		ReadTicks:    stats[3],
		WriteIOs:     stats[4],

		color.YellowBold(topLeftChar + strings.Repeat(horizBarChar, maxContentWidth) + topRightChar),
		color.YellowBold(vertBarChar) + line1InColor + strings.Repeat(" ", maxContentWidth-line1Length) + color.YellowBold(vertBarChar),
		color.YellowBold(vertBarChar) + line2InColor + strings.Repeat(" ", maxContentWidth-line2Length) + color.YellowBold(vertBarChar),
		color.YellowBold(bottomLeftChar + strings.Repeat(horizBarChar, maxContentWidth) + bottomRightChar),
	}

- 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.

	return []byte{letterBytes[rand.Intn(len(letterBytes))]}

func generateBytesData(size int) []byte {
	// repeat the random character chosen size
	return bytes.Repeat(getRandomByte(), size)
}

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.
