levit_monitor #

Purpose & Scope #

levit_monitor is the diagnostics and event export layer for Levit runtimes.

This package is responsible for:

• Capturing structured runtime events from DI and reactive layers.
• Filtering and obfuscating payloads before export.
• Dispatching events through pluggable transports.
• Maintaining optional in-memory shadow state for debugging workflows.

This package does not include:

• Visualization UI or dashboards.
• Business logic instrumentation outside the Levit runtime event model.

Conceptual Overview #

Monitoring is opt-in. Calling LevitMonitor.attach() installs middleware into the runtime. Event flow:

1. Runtime emits DI/reactive events.
2. Filter decides whether to forward the event.
3. Obfuscator redacts sensitive values.
4. Transport(s) deliver encoded events.

Getting Started #

dependencies:
  levit_monitor: ^latest

import 'package:levit_monitor/levit_monitor.dart';

void main() {
  LevitMonitor.attach(
    transport: ConsoleTransport(),
    filter: (event) => true,
  );
}

Design Principles #

• Opt-in instrumentation with explicit attach/detach lifecycle.
• Transport-agnostic event delivery.
• Privacy-aware output through obfuscation hooks.
• Low-friction integration with existing Levit middleware semantics.
