- Rust is increasingly used for high-performance systems and developer tools.
- Observability in Rust applications is crucial despite Rust's correctness guarantees.
- OpenTelemetry (OTel) standardizes telemetry data generation and collection.
- OTel avoids vendor lock-in by decoupling instrumentation from backends.
- Rust's OTel implementation differs from languages like Python due to its compiled nature.
- The demo uses Tokio for async execution and tracing for telemetry.
- SigNoz is used as the OTel-native backend for visualization.
- Key steps include setting up OTel providers for traces, metrics, and logs.
- Trace context propagation is demonstrated across services.
- Metrics like active requests and request duration help monitor system health.
