Sunny	3dbe870455	monitoring: Configure KSM & cluster dashboard Update kube-prometheus-stack helm release values to configure kube-state-metrics and use kube-state-metrics to collect gotk resource state metrics. - Configure kube-state-metrics to run in custom resource state only mode. In this mode, it'll only watch custom resources. Also, pass empty collectors as extra args to prevent passing all the core resources to watch as an argument. - Running kube-state-metrics in custom resource state only mode makes the default grafana dashboards of no use. Disable the default dashboards. - Add kube-state-metrics configuration to provide RBAC permissions to it to allow listing and watching flux CRDs. - Also, configure custom resource state for each of the flux custom resources using Info type metrics called `gotk_resource_info`. KSM issues a warning if an Info type object doesn't have `_info` suffix. These metrics have the value 1 always. This works well for the CRD state metrics as a zero value would mean that the resource doesn't exist, in which case, the resource is deleted. - Update the cluster dashboard panels to use `gotk_resource_info` in the queries. - Only the following panels have been updated - Cluster Reconcilers - Failing Reconcilers - Cluster reconciliation readiness - Kubernetes Manifests Sources - Failing Sources - Source acquisition readiness - The panels have been updated such that it's work with static resources which don't have any status as well. By default, it assumes such static resources to be in a Ready state. Resources are seen as failed only when the ready value is false. - The queries have been updated to Instant type in order to show the current data, instead of the result of past 15 minutes. This shows more accurate resource data as the resource metrics change. - The Stat visualizers have been updated to have zero as the default value when there's no data. This is to prevent showing no data when there's no object. This was motivated by the behavior of the previous configuration which depended on stale metrics from controllers and deleted conditions to show zero value when objects get deleted. With the fixes in the controller metrics that removes stale metrics, this will no longer work. In order to show a zero value for these stats, a default is set. - The `$namespace` variable has been updated to refer to `exported_namespace` from `gotk_resource_info`.
