Meet Mimir — a possible thanos replacement that boasts lower CPU, memory and storage usage, fast query latency and great performance.

Developed by Grafana Labs, Mimir collects and stores more information for comparative analysis by integrating into an observability stack with Grafana, Loki and Tempo. Its regional persistent disk design permits metric storage indefinitely and cost-efficiently, making the operation of the system more manageable.

Though like any solution, dedicated effort and understanding are required, Mimir provides an alternative for historical metric collection and storage.
