      With this release, you can now specify resource requests and limits for all monitoring components, including the following:

      * Alertmanager
      * kube-state-metrics
      * node-exporter
      * openshift-state-metrics
      * Prometheus
      * Prometheus Operator and its Admission webhook
      * Telemeter Client
      * Thanos Querier
      * Thanos Ruler

      In previous versions of {product-title}, you could only set options for Prometheus, Alertmanager, Thanos Querier, and Thanos Ruler.

    Description

      Epic Goal

      • Users can today specify resource requirements for some of the components:
        • Prometheus (in-cluster and UWM), only for the prometheus container.
        • Alertmanager (in-cluster and UWM), only for the alertmanager container.
        • Thanos Querier, only for the thanos-query container.
        • Thanos Ruler, only for the thanos-ruler container.
      • We should extend that too all containers, that potentially use too many resources.
      • Similar configuration options might be exposed for other components (subject for evaluation)
        • Node exporter
        • Kube state metrics
        • OpenShift state metrics
        • prometheus-adapter
        • prometheus-operator + admission webhook (platform and UWM)
        • telemeter-client
