+## Monitor Lifecycle
+
+1. A monitor executes a check (HTTP / ping / port / hardware via Capture agent)
+2. The result is stored (success/failure + response time)
+3. The system evaluates recent checks to determine status (up/down)
+4. If failure threshold is reached, the monitor becomes "down"
+5. If it stays down, an incident is created automatically
+6. Notifications are triggered based on configuration
