Example: Limit a MinIO cluster to accept at max 1600 simultaneous S3 API requests across all nodes of the cluster.

```sh
export MINIO_API_REQUESTS_MAX=1600
export MINIO_ROOT_USER=your-access-key

The command will generate the `scrape_configs` section of the prometheus.yml as follows:

## Introduction

This chart bootstraps MinIO Cluster on [Kubernetes](http://kubernetes.io) using the [Helm](https://helm.sh) package manager.

## Prerequisites

- Helm cli with Kubernetes cluster configured.
- PV provisioner support in the underlying infrastructure. (We recommend using <https://github.com/minio/direct-csi>)
