When it comes to Prometheus and alerts, the typical use case is to send alerts to Alertmanager for handling (deduplication, grouping) and routing them to the various services such Slack, PagerDuty etc.

In this post, I will share how we can visualize the alert metrics on Grafana using the various PromQL operators and functions.
