Kube State Metrics

This package provides kube-state-metrics service which listens to Kubernetes API server and generates metrics about the state of Kubernetes objects like Deployments, Nodes, or Pods.

From kube-state-metrics repository:

That kube-state-metrics is about generating metrics from Kubernetes API objects without modification. This ensures, that features provided by kube-state-metrics have the same grade of stability as the Kubernetes API objects themselves. In turn, this means, that kube-state-metrics in certain situations may not show the same values as kubectl, as kubectl applies certain heuristics to display comprehensible messages. kube-state-metrics exposes raw data unmodified from the Kubernetes API, this way users have all the data they require and perform heuristics as they see fit.
