Fleet Telemetry & Alerting System
Design a system for a logistics company to monitor a fleet of vehicles in real-time. Each vehicle periodically sends telemetry data (GPS, fuel level, engine temperature). The system must allow fleet managers to define dynamic alerting rules (e.g., 'Alert if fuel < 10% AND vehicle is more than 50 miles from a depot'). Rules vary by vehicle type (Truck vs. Drone) and must be pluggable without restarting the system. Additionally, the system should support different notification sinks like SMS, Email, or a real-time Dashboard.
