Grafana Mimir is an open source, horizontally scalable, highly available, multi-tenant time series database providing long-term storage for Prometheus and OpenTelemetry metrics. It supports PromQL, remote write, alerting, and durable storage on object stores like S3, GCS, and Azure Blob Storage, tested to 1 billion active series.

Use cases

• store prometheus metrics long-term at scale
• run a multi-tenant metrics backend for multiple teams
• query metrics from multiple prometheus instances with a global view
• replace thanos or cortex for scalable metrics storage
• ingest opentelemetry and influx metrics into one tsdb
• set up centralized prometheus alerting and recording rules

When to choose

• you need to scale beyond a single prometheus instance to billions of active series
• you want multi-tenant isolation with per-team limits and QoS controls
• you need highly available metrics storage with zero-downtime upgrades
• you want durable, cheap long-term storage on object storage backends

When to avoid

• you only need a single-node prometheus setup with modest retention
• you primarily need log or trace storage rather than metrics
• you cannot comply with the AGPLv3 license
• you want a fully managed service without operating a cluster
