<p>What is the best way for monitoring Kubernetes Cluster. I have a social network website builded with nodejs and react. I need to know how much app resources I need per user (example: for 100 user per hour we must have 3 replcias of backend)
What is the best solution to do this?</p>

<p>I saw based on the comment of a previous answer that you are using Rancher.</p>

<p>Rancher's 2.2 version includes the ability to deploy in-cluster monitoring using Prometheus and Grafana. </p>

<p>Check out <a href="https://rancher.com/docs/rancher/v2.x/en/cluster-admin/tools/monitoring/" rel="nofollow noreferrer">https://rancher.com/docs/rancher/v2.x/en/cluster-admin/tools/monitoring/</a> for a breakdown of this. It's super simple to setup and get going. </p>
