<p>I have a spring boot application which is running in a Kubernete cluster successfully. But now I want to scale the application when we receive more traffic. So what are the metrics that I should consider if I am using Prometheus/Grafana combination in my application? The prometheus gives me lots of metrics, but I am a bit confused about which one should I use for HPA (Horizontal Pod scaling).</p>

<p>Also, you should install the metric server <a href="https://github.com/kubernetes-sigs/metrics-server" rel="nofollow noreferrer">https://github.com/kubernetes-sigs/metrics-server</a> before creating HPA</p>
