Logging Tracing and Debugging Questions

Covers design and implementation of observability and diagnostic tooling used to troubleshoot applications and distributed systems. Topics include structured machine readable logging, log enrichment with context and correlation identifiers, log aggregation and indexing, retention and cost trade offs, and searchable queryability. It also includes distributed tracing to follow request flows across services, trace sampling and propagation, and correlating traces with logs and metrics. For debugging, include production safe debugging techniques, live inspection tools, core dump and profiling strategies, and developer workflows for reproducing and isolating issues. Reporting aspects cover test and run reporting, generating dashboards and HTML reports, capturing screenshots or video on failure, and integrating diagnostic output into continuous integration and monitoring pipelines. Emphasize tool selection, integration patterns, alerting on diagnostic signal, privacy and security considerations for logs and traces, and practices that make telemetry actionable for incident response and postmortem analysis.
