PulseGuard: Real-Time Incident Observability with Java, OpenTelemetry & SigNoz

PulseGuard is a local Java observability demo for a simulated e-commerce checkout flow.

It uses OpenTelemetry and the Java agent to capture traces, metrics, and alerts.

SigNoz visualizes latency, errors, and service health across checkout, payment, and inventory services.

The demo highlights how real-time telemetry can reveal degraded payment scenarios and other issues early.
