NestJS Observability

Implement structured logging in NestJS by configuring the nestjs-pino module to output high-performance JSON logs. This setup injects request context and applies mandatory redaction to sensitive fields for secure observability.

Trace requests across NestJS microservices by injecting a correlation ID into every log line as a reqId. This ID correlates logs across all downstream systems to debug complex transactions effectively.

Expose Prometheus metrics in a NestJS application by integrating the @willsoto/nestjs-prometheus module. This sets up dedicated endpoints to expose key application performance indicators for monitoring.

Set up health checks for NestJS using Terminus to define liveness and readiness probes. This integration monitors critical dependencies like database connectivity and memory usage to prevent crashes.

Add observability to a NestJS app by combining structured logging, request tracing, and Prometheus metrics. This approach provides comprehensive application insight by correlating requests and monitoring performance indicators.

Yes, this NestJS observability setup supports log redaction through the nestjs-pino module. It enforces mandatory redaction of sensitive fields within your structured JSON logs to ensure secure monitoring.
