Dalton Hubble 178afe4a9b Reduce apiserver metrics cardinality and extraneous labels ... * Stop mapping node labels to targets discovered via Kubernetes nodes (e.g. etcd, kubelet, cadvisor). It is rarely useful to store node labels (e.g. kubernetes.io/os=linux) on these metrics * kube-apiserver's apiserver_request_duration_seconds_bucket metric has a high cardinality that includes labels for the API group, verb, scope, resource, and component for each object type, including for each CRD. This one metric has ~10k time series in a typical cluster (btw 10-40% of total) * Removing the apiserver request duration outright would make latency alerts a NoOp and break a Grafana apiserver panel. Instead, drop series that have a "group" label. Effectively, only request durations for core Kubernetes APIs will be kept (e.g. cardinality won't grow with each CRD added). This reduces the metric to ~2k unique series		2019-12-08 22:48:25 -08:00
