Since its launch in 2012, Prometheus has become the standard technology to collect metrics in a Kubernetes cluster. Prometheus pulls (scrapes) real-time metrics from application services and hosts by sending HTTP requests on Prometheus metrics exporters. It then compresses and stores them in a time-series database on a regular cadence. The new can collect metrics exposed by your exporters. This means Dynatrace isn’t collecting the metrics on the Prometheus server, but directly at the source of truth – the exporters.
