<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>Look at prometheus Operator.

<p>It would setup all required modules to monitor the kubernetes cluster resources.
you can even define rules and if the thresholds are beached send a notifications via alert manager.</p>

<p>you might need to do little tweaking of some of the services, particularly the stateful pod like prometheus. It would pretty much sets up dashboards and all required to review the metrics and see what is going on in the k8s cluster</p>
