As already mentioned in this issue https://github.com/kubernetes/kubernetes/issues/79286, some metrics like "running_pod_count" and "running_container_count" uses non-standard prometheus metrics, this change converts them to be standard prometheus gauges Minor refactor in kubelet/pleg/generic.go and added some test for ruuning container and running pod metrics Fixed issues related to github CI pipeline failure * Updated bazel for new deps * Add comment for exported metrics variables,RuuningContainerCount and RunningPodCount * Specify keys explicitly in Guage metric instantation Fix go lint errors Replace "+=1" with "++", as reported by go lint Set container state as a label for the metrics "running_container_count" As per the metrics name "running_container_count" it should "ideally" be showing the number of containers in "running" state , but it was showing all the container count, irrespective of the state it is in. This commit adds a new label "container_running_state" to the metrics "running_container_count", which doesn't change the base metrics but adds the option to query the metrics with "container_state" such as "running"/"unknown/... remove unused methods reported by staticcheck Remove variables while instantiating gauge(vec) which are default set to nil Convert kubelet metrics(running_pod_count and running_container_count) to standard gauges and added label to running_container_count metrics. Currently kubelet metrics(running_pod_count and running_container_count) use non-standard prometheus collectors , this change converts them to standard prometheus gauges. Also this adds a new label(container_state) to running_container_count which does a breakdown of containers tracked by kubelet based on the containers' state(running/unknown/created/exited). Set statbility explicitly for running_pod_count and running_container_count and reformat test register metrics explicitly in test , so that they don't become no-op |

Kubernetes
Kubernetes is an open source system for managing containerized applications across multiple hosts; providing basic mechanisms for deployment, maintenance, and scaling of applications.
Kubernetes builds upon a decade and a half of experience at Google running production workloads at scale using a system called Borg, combined with best-of-breed ideas and practices from the community.
Kubernetes is hosted by the Cloud Native Computing Foundation (CNCF). If you are a company that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details about who's involved and how Kubernetes plays a role, read the CNCF announcement.
To start using Kubernetes
See our documentation on kubernetes.io.
Try our interactive tutorial.
Take a free course on Scalable Microservices with Kubernetes.
To start developing Kubernetes
The community repository hosts all information about building Kubernetes from source, how to contribute code and documentation, who to contact about what, etc.
If you want to build Kubernetes right away there are two options:
You have a working Go environment.
go get -d k8s.io/kubernetes
cd $GOPATH/src/k8s.io/kubernetes
make
You have a working Docker environment.
git clone https://github.com/kubernetes/kubernetes
cd kubernetes
make quick-release
For the full story, head over to the developer's documentation.
Support
If you need support, start with the troubleshooting guide, and work your way through the process that we've outlined.
That said, if you have questions, reach out to us one way or another.
