# Why are my metrics missing in Grafana?

Work through these checks before contacting [Support](/support/contact):

* **Wrong data source for your cluster's region.** The most common cause. Verify the dashboard's data source matches the Super Region where your cluster runs. See [Data sources](/observability/logs-metrics/data-sources) for the region-to-endpoint mapping.

* **Missing IAM role.** Your user needs the `Observability Viewer` role to see any dashboards, plus `Billing Viewer` for the Usage by Product and Zone dashboard.

* **Invalid API token** (direct API or self-hosted Grafana). Every request must include a valid `Authorization: Bearer [ACCESS-TOKEN]` header. Test it:

  ```bash theme={"system"}
  curl -G "https://observe.coreweave.com/api/v1/query" \
    -H "Authorization: Bearer [ACCESS-TOKEN]" \
    --data-urlencode "query=up"
  ```

  If it fails, generate a new API Access Token.

* **No Prometheus Operator on the cluster.** Clusters created after July 7, 2025 do not ship with it, so custom application metrics are not collected. Install it and add a `PrometheusAgent` with `remoteWrite`. See [Forward application metrics](/observability/logs-metrics/forward-metrics).

* **Billing metric inflated by control plane Nodes.** Clusters created before July 7, 2025 include a non-billable `cpu-control-plane` Node Pool. Filter with `billing:instance:total{node_pool_name!="cpu-control-plane"}`. See [Usage monitoring](/observability/usage-monitoring).

* **Log expired.** Some log classes expire after two weeks. If a log is missing from your Super Region, check the legacy endpoint `observe-legacy.coreweave.com`.
