Monitoring Tools

Guardian's monitoring tools provide infrastructure for external systems to observe and react to Guardian's internal event stream without requiring a direct NATS connection.

Application Events Module

The Application Events Module is a standalone HTTP service (port 3012) that:

• Subscribes to all Guardian NATS event subjects on startup

• Exposes a REST API for registering and managing webhooks

• Delivers events to registered webhook URLs via HTTP POST

• Provides a streaming JSON endpoint for real-time event consumption
