Project Introduction

Summary

Grafana Mimir is an open-source, horizontally scalable, highly available, multi-tenant, long-term storage system for Prometheus. It's designed to provide a robust backend for your metrics, allowing you to scale your monitoring infrastructure efficiently and reliably.

Problem Solved

Prometheus is excellent for real-time monitoring but faces challenges with long-term data retention, high availability, and scaling for very large environments or multi-tenant use cases. Grafana Mimir addresses these limitations.

Core Features

Horizontal Scalability

Scale your Prometheus monitoring data horizontally to handle massive ingest and query volumes.

High Availability

Ensure your metrics data is always available, even during outages or component failures.

Multi-Tenancy

Safely and securely store metrics from multiple independent teams or clients within a single Mimir cluster.

Long-Term Storage

Retain your valuable Prometheus metrics for months or years, far beyond the capabilities of standalone Prometheus.

Tech Stack

Go
gRPC
Protobuf
OpenTelemetry
Prometheus (remote write/read)
Object Storage (S3, GCS, Azure Blob, etc.)

Use Cases

Grafana Mimir is suitable for various scenarios where enhanced Prometheus capabilities are required:

Large-Scale Metrics Collection

Details

Companies with large fleets of servers or applications can use Mimir to ingest metrics from thousands or millions of active series without data loss or performance degradation.

User Value

Ensures reliable monitoring coverage across the entire infrastructure.

Offering Multi-Tenant Monitoring Services

Details

Managed service providers or internal platform teams can offer Prometheus-as-a-Service to different clients or departments, keeping their data separate and secure.

User Value

Provides strong isolation and efficient resource utilization for multiple users.

Long-Term Historical Data Retention

Details

Organizations needing to store metrics for compliance, historical analysis, or trend identification over extended periods (months or years).

User Value

Enables deep historical analysis, compliance reporting, and capacity planning based on long-term trends.
