Day 36: Alert Models & Rules - Building Intelligent Alert Management
Working Code Demo:
What We’re Building Today
Today we’re constructing the brain of our monitoring system - the Alert Models & Rules engine. Think of it as the decision-making center that knows when to wake up your team at 3 AM versus when to quietly log an issue.
Key Components:
Alert rule models with flexible threshold definitions
State-driven alert lifecycle management
Escalation policies that understand urgency
Smart suppression logic to prevent alert storms
Why This Matters in Real Systems
Every time you get a Slack notification from your deployment pipeline, or when PagerDuty pages an engineer - that’s an alert system at work. Companies like Netflix process millions of metrics per second and need intelligent rules to distinguish between “database connection hiccup” and “entire service is down.”
Without proper alert models, you get either silence when things break or constant noise that engineers ignore. Both scenarios cost companies millions.
