![Two alerting paths: Prometheus rules and Grafana-managed rules can both send alerts to an external Alertmanager](https://n9e.io/assets/images/grafana-alerting-vs-alertmanager-41493bc27d0f814667ae50923227c1ad.webp)

**Choose Prometheus with Alertmanager when your rules belong with your metrics and are maintained as code. Choose Grafana-managed alerting when you need Grafana to evaluate queries across supported data sources and manage conditions through its UI or provisioning tools.** You can also keep Prometheus rules, add Grafana-managed rules for other data, and use the same external Alertmanager for notification delivery.

The important decision is where a rule runs and who owns its notifications. Here is how to make those choices without evaluating the same condition twice.
