Mimir

Overview

Grafana Mimir is the Prometheus-compatible metrics backend used by the WxCDI dashboards and metric alerts. Prometheus instances scrape targets locally and remote-write samples into Mimir.

Architecture

Prometheus instances → remote write → Mimir → Grafana dashboards and alerts

The detailed topology, storage backend, and component versions are controlled by the shared metrics platform and current deployment configuration.

Querying

Use Grafana Explore or dashboard panels with PromQL. When Grafana is missing recent data but a Prometheus scrape succeeds, check remote-write queue/errors, tenant routing, Mimir ingestion, and the Grafana data source before changing the dashboard.

Retention Policy

The reviewed repositories do not contain a verified retention value. Confirm retention and historical-data commitments with the Mimir service owner.

Administration

Scaling, tenancy, object storage, compaction, retention, and global availability changes require the shared platform's approved change process. WxCDI engineers should focus on scrape health, remote-write health, query correctness, and label/cardinality quality.
