Find centralized, trusted content and collaborate around the technologies you use most. However, it's not exactly importing, but rather relying on a scrape target that gradually gives old metrics data (with custom timestamp). The API accepts the output of another API we have which lets you get the underlying metrics from a ReportDataSource as JSON. Valid workaround, but requires prometheus to restart in order to become visible in grafana, which takes a long time, and I'm pretty sure that's not the intended way of doing it. Prometheus has become the most popular tool for monitoring Kubernetes workloads. Prometheus stores data as a time series, with streams of timestamped values belonging to the same metric and set of labels. :-). If a target is removed, its previously returned time series will be marked as How to show that an expression of a finite type must be one of the finitely many possible values? Prometheus UI.
