GitHub - cortexproject/cortex: A horizontally scalable, highly available, multi-tenant, long term Prometheus.
Cortex provides horizontally scalable, highly available, multi-tenant, long term storage for Prometheus. Horizontally scalable: Cortex can run across multiple machines in a cluster, exceeding the throughput and storage of a single machine. This enables you to send the metrics from multiple Prometheus servers to a single Cortex cluster and run "globally aggregated" queries across all data in a single place.
