Stand up Grafana Mimir for horizontally scalable, multi-tenant, long-term Prometheus + OTLP metrics storage. Covers monolithic / read-write / microservices deployment, S3 / GCS / Azure / filesystem block storage, Prometheus \`remote\_write\` and OTLP ingestion, multi-tenancy with \`X-Scope-OrgID\`, ingester replication factor, compactor retention, and per-tenant limits. Use when running Mimir locally or on Kubernetes (Helm \`mimir-distributed\`), scaling Prometheus past a single node, picking ingest / query / backend split, configuring tenants and ingestion rate, debugging \`/ready\` 503s or \`429 Too Many Requests\`, or pointing Grafana at a Mimir datasource — even when the user says "I need long-term Prometheus storage", "scale Prometheus", "multi-tenant metrics backend", "Cortex replacement", "remote\_write target", or "store 10M active series" without naming Mimir.

## Install

```sh
git clone https://github.com/grafana/skills /tmp/skills && ln -s /tmp/skills/skills/grafana-lgtm/mimir ~/.claude/skills/mimir
