Mimir / Sizing

Capacity-planning / sizing dashboard for a Grafana Mimir microservices deployment running on Kubernetes, based on the recommendations in Grafana's own Planning capacity guide.

For each component (distributor, ingester, query-frontend, query-scheduler, querier, store-gateway, ruler, compactor, alertmanager, caches) it compares:

• Required CPU / memory / disk, estimated from current load using the ratios from that guide
• Actual CPU / memory requested (Kubernetes resource requests)
• Used CPU / memory / disk (actual consumption)

so you can see at a glance whether each component is under- or over-provisioned, plus a replica-scaling table and read/write-path diagrams showing the highest-utilised resource per service.

Data sources

• Prometheus (required): scraping Mimir's own metrics (cortex_*) plus Kubernetes cluster metrics. The latter are fully covered by the grafana/k8s-monitoring-helm chart with clusterMetrics.enabled: true (kube-state-metrics, cAdvisor and kubelet sub-collectors, all on by default), which supplies every raw metric this dashboard needs (kube_pod_container_resource_requests, container_cpu_usage_seconds_total, container_memory_working_set_bytes, kubelet_volume_stats_*_bytes, kube_pod_owner, etc.) with the expected kube-state-metrics / kubelet job labels. You'll additionally need the kubernetes-mixin and mimir-mixin recording rules evaluated on top of those metrics (e.g. loaded into your Mimir ruler or Prometheus); the collector chart doesn't ship rule evaluation itself.
• Loki (optional): only used for the disabled-by-default "Kubernetes events" annotation. Enable clusterEvents.enabled: true in the same chart, its default jobLabel: "integrations/kubernetes/eventhandler" is exactly what the annotation query expects, no extra config needed.

Variables: $datasource / $loki_datasource (pick your Prometheus/Loki), $cluster, $namespace (auto-populated from cortex_build_info), $timeshift (comparison window for the "previous period" panels, e.g. 24h, 7d).

Requires the Diagram panel plugin (jdbranham-diagram-panel) for the two read/write architecture panels.
