Also, note that the certificate has to contain the `Extended Key Usage: TLS Web Client Authentication`. Otherwise, MinIO would not accept the certificate as client certificate.

Now, the STS certificate-based authentication happens in 4 steps:

- Client sends HTTP `POST` request over a TLS connection hitting the MinIO TLS STS API.
- MinIO verifies that the client certificate is valid.
- MinIO tries to find a policy that matches the `CN` of the client certificate.

## Prerequisites

To get started with MinIO, refer [MinIO QuickStart Document](https://docs.min.io/community/minio-object-store/operations/deployments/baremetal-deploy-minio-on-redhat-linux.html).
Follow below steps to get started with MinIO monitoring using Prometheus.

### 1. Download Prometheus

[Download the latest release](https://prometheus.io/download) of Prometheus for your platform, then extract it

Here's a little bit of that history.

        while (!rdmaConnection.canSend() && System.currentTimeMillis() < deadline) {
            try {
                Thread.sleep(10);

                Thread.currentThread().interrupt();

            }
        }

With fast fallback, OkHttp attempts to connect to multiple web servers concurrently. It keeps whichever route connects first and cancels all of the others. Its rules are:

 * Prefer to alternate IP addresses from different address families, (IPv6 / IPv4), starting with IPv6.

// ReplicationLastHour keeps track of replication counts over the last hour
