Observing your applications with Sentry and Prometheus
summary
Explains how Sentry and Prometheus are actually used to catch production failures early with concrete examples and code snippets: Sentry aggregates events and sends one notification per unique error while capturing stack traces and local variables; Prometheus pulls metrics via an HTTP endpoint using start_http_server and records counters gauges and histograms; shows Flask/Django integration and a working alert rule that predicts disk growth so ops get notified before outages occur and dashboards are built in Grafana.
