## Prerequisites

- Prometheus and MinIO configured as explained in [document here](https://github.com/minio/minio/blob/master/docs/metrics/prometheus/README.md).
- Grafana installed as explained [here](https://grafana.com/grafana/download).

In a real world scenario, including initialization and reader overhead from varying blob sizes, performance can be expected as below:

  * Update the command section in each service.
  * Add a new MinIO server instance to the upstream directive in the Nginx configuration file.

`/<user-running-minio>/.minio/certs`.

*Tip*: In a standard Kubernetes configuration, this will be `/root/.minio/certs`. Kubernetes will mount the secrets volume read-only,

fs.s3a.max.total.tasks=2048 # Maximum number of parallel tasks
fs.s3a.multipart.size=512M # Size of each multipart chunk
fs.s3a.multipart.threshold=512M # Size before using multipart uploads
fs.s3a.socket.recv.buffer=65536 # Read socket buffer hint
fs.s3a.socket.send.buffer=65536 # Write socket buffer hint
fs.s3a.threads.max=2048 # Maximum number of threads for S3A
```

The rest of the other optimization options are discussed in the links below

After Prometheus is configured, you can use Grafana to visualize MinIO metrics. Refer the [document here to setup Grafana with MinIO prometheus metrics](https://github.com/minio/minio/blob/master/docs/metrics/prometheus/grafana/README.md).

## List of metrics exposed by MinIO

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