Hi all,
As part of a development project I am currently diving a bit deeper into the topic of monitoring in Kubernetes. I have no issues with the setup and monitoring pipelines. I have both the metrics server and Prometheus monitoring up and running fine. However, as the topic states, I would like to know which Kubernetes components use/can use monitoring data from the cluster.
What do I mean with "Kubernetes components or activities"?
Obviously, one of the main use cases for monitoring data are all autoscaling mechanisms, including Horizontal Pod Autoscaler, Vertical Pod Autoscaler and Cluster Autoscaler. I am searching for further components or activities, which use live monitoring data from a Kubernetes cluster, and potentially a short explanation why they use it (if it is not obvious). Also it would be interesting to know, which of those components or activities must work with monitoring data and which can work with monitoring data, i.e. can be configured to work with monitoring data.
What do I mean with "monitoring data"?
Monitoring data include, but are not limited to: Node metrics, Pod metrics, Container metrics, network metrics and custom/application-specific metrics (e.g. captured and exposed by third-party tools like Prometheus).
With this issue, I hope a get some insight from different Kubernetes users or sigs. I am thankful for every answer or comment in advance!
