Prometheus

Prometheus is an open source monitoring tool, a Cloud Native Computing Foundation graduated project. It can be installed on premises, has Docker images, comes out-of-the-box on IBM OpenShift.

Prometheus is a dimensional, polling monitoring system. This means it pulls data from Keep periodically, by default at one minute intervals.

Grafana can be used to generate dashboards using the time-shift data Prometheus collects.
