Allowed values: + - `cluster` + - `namespace` + +Notes: +- **Stability**: + - The id is **always derived from the rule spec**. If the rule definition changes (expr/for/business labels/name), the id may change. + - For **platform rules**, this API currently only supports label updates via `AlertRelabelConfig` (not editing expr/for), so the id is effectively stable unless the upstream operator changes the rule definition. + - For **user-defined rules**, the API stamps the computed id into the `PrometheusRule` rule labels. If you update the rule definition, the API returns the **new** id and migrates any existing classification override to the new id. +- Layer values are validated as `cluster|namespace` when set.

When the client does not provide a `namespace` filter, the plugin discovers candidate namespaces and queries Thanos tenancy per-namespace, using the end-user bearer token. + +Routes in `openshift-user-workload-monitoring` are treated as **fallbacks** (and are also used for some health checks and pending state retrieval). + +If you want to create the user workload Prometheus route (optional), you can expose the service: + +```shell +oc -n openshift-user-workload-monitoring expose svc/prometheus-user-workload-web --name=prometheus-user-workload-web --port=web +``` + +If the route is missing/unreachable but tenancy is healthy, the plugin should still return user workload data and suppress route warnings. + +#### Alert states + +- `/api/v1/alerting/alerts?state=pending`: pending alerts come from Prometheus. +- `/api/v1/alerting/alerts?state=firing`: firing alerts come from Alertmanager when available. +- `/api/v1/alerting/alerts?state=silenced`: silenced alerts come from Alertmanager (requires an Alertmanager endpoint). + +### Alertmanager routing choices + +OpenShift supports routing user workload alerts to: + +- The **platform Alertmanager** (default instance) +- A **separate Alertmanager** for user workloads +- **External Alertmanager** instances + +This is a cluster configuration choice and does not change the plugin API shape. The plugin reads alerts from Alertmanager (for firing/silenced) and Prometheus (for pending), then merges platform and user workload results when available. + +The plugin intentionally reads from only the in-cluster Alertmanager endpoints. Supporting multiple external Alertmanagers would introduce ambiguous alert state and silencing outcomes because each instance can apply different routing, inhibition, and silence configurations. diff
