Thanos

Open source, highly available Prometheus setup with long-term storage capabilities. Scale your Prometheus setup by enabling querying of your Prometheus metrics across multiple Prometheus servers and clusters. Extend the system with the object storage of your choice to store your metrics for an unlimited time. Supports GCP, S3, Azure, Swift and Tencent COS. Use the same tools you love, such as Grafana and others, that support the Prometheus Query API. Downsample historical data for massive query speedup when querying large time ranges or configure complex retention policies. Thanos leverages the Prometheus 2.0 storage format to cost-efficiently store historical metric data in any object storage while retaining fast query latencies. Additionally, it provides a global query view across all Prometheus installations and can merge data from Prometheus HA pairs on the fly.
