Prometheus

Prometheus is an open source monitoring system that collects metrics from services and evaluates alert rules against them. This tag collects guides about monitoring RSS and Atom feeds with Prometheus. Articles explain how to probe a feed address with the blackbox exporter, how to check the status, the duration and the certificate and how to confirm that the body is really a feed. They also cover a short script that exports the number of items and the date of the newest one through the textfile collector, alert rules for feeds that are down, empty or stale, thresholds that match a publishing rhythm and dashboards. The advice helps teams notice a silent feed before readers do.
