Benchmarking Grafana Enterprise Metrics for horizontally scaling Prometheus up to 500 million active series
Since we launched Grafana Enterprise Metrics (GEM), our self-hosted Prometheus service, last year, we’ve seen customers run it at great scale. We have clusters with more than 100 million metrics, and GEM’s new scalable compactor can handle an estimated 650 million active series. Still, we wanted to run performance tests that would more definitively show GEM’s horizontal scalability and allow us to get more accurate TCO estimates.
