So what does this really mean... well, it means supporting prometheus in cluster mode. It will expose a cluster metrics route, allowing a visualization tool such as Grafana, DataDog and others, to visual performance metrics of the application itself. This, coupled with node-exporter-prometheus, we can gain per route performance metrics that can be exposed to the promql language and again, be visualized.
