This stack is meant for cluster monitoring, so it is pre-configured to collect metrics from all Kubernetes components. You get the metrics details by querying from the Prometheus's time-series database where the Prometheus stores metrics and you use a query language called PromQL in the Prometheus server to query metrics about the targets. There are a number of libraries and servers which help in exporting existing metrics from third-party systems as Prometheus metrics.
