# Watch requests move through every application tier.

> TrafficWar Live Map visualizes real-time request flow, latency, errors, routes, services, databases, Redis, and S3 dependencies.

TrafficWar converts incoming spans into an interactive system map so a changing route, slow dependency, or error spike is visible while it happens.

## A map built from your event stream

Each event supplies the route, source, operation, latency, status, and optional trace identity. TrafficWar groups those signals into tier-aware stations instead of asking you to infer a request path from unrelated charts.

HTTP client and server spans form the edge and backend tiers. Database, Redis, and S3 events form infrastructure stations. S3 providers or bucket-qualified sources can appear as separate stations while operation types remain the activity dots.

## Designed for live investigation

- See request volume, latency classes, and failures as events arrive.
- Select a request journey to inspect its tier-by-tier waterfall.
- Filter by service and keep the visualization scoped to one tenant.
- Pause or reduce motion without losing the underlying metrics.

## Use the map with metrics and traces

The Live Map is an investigation surface, not a replacement for historical analysis. Follow a route into Metrics for percentiles, Explore for raw events, or Traces for the complete request waterfall.
