Ep4 Prometheus Alerts to Slack | Real-Time Alertmanager Integration Monitoring & Alerting

Welcome to Episode 4 of the Monitoring & Alerting in Real Life series!
In this video, we bring your alerting system to life — by connecting Prometheus + Alertmanager + Slack for real-time production notifications.

When something goes wrong, you shouldn’t find out from users — you should find out from your alert system first.
This episode teaches exactly how to make that happen.

🎯 What You’ll Learn:

What are Prometheus alerts and how they work

Writing alert rules in alert_rules.yml

Setting up Alertmanager for routing alerts

Sending Slack notifications using webhook integrations

Grouping, deduplication, and repeat intervals

Testing real-world outage alerts in Docker

🧩 Tech Stack:
Prometheus, Alertmanager, Grafana, Docker Compose, Flask App, Slack Webhooks

💡 By the End:
You’ll have a production-grade alerting pipeline where every warning and critical error triggers an instant Slack message — just like in real SRE setups.
