☸️Monitoring

Describe about Monitoring

In Kubernetes, there isn't a fully built-in feature for monitoring, but open-source solutions like Metric Server, Prometheus, ElasticStack, etc., can be utilized. Previously, Kubernetes had Heapster as a project for enabling monitoring, but it has been deprecated. The subsequent version now relies on Metric Server for this purpose.
