<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>The only valid way is to do stress testing (using for example AB or Jmeter) of your application and monitoring consumed resources using Prometheus and Grafana. You probably should also enable Horizontal Pod Autoscaler for your application to test how it scales with load.</p>

<p>If you don't have Prometheus and Grafana - here is a simple but powerful instruction way to install it: <a href="https://github.com/coreos/kube-prometheus" rel="nofollow noreferrer">https://github.com/coreos/kube-prometheus</a></p>
