Structured logging with JSON formats involves creating actionable data trails that are easy to parse and search. You implement this by formatting service logs as JSON objects, enabling efficient debugging and analysis of specific error messages across your system.

Debugging a slow distributed system endpoint is best achieved by analyzing distributed tracing data to pinpoint bottlenecks. You instrument code using OpenTelemetry to visualize request flows across services, then examine structured logs for related errors.

Distributed tracing with OpenTelemetry improves system observability by visualizing request flows across multiple services. This instrumentation creates actionable data trails that help you track requests end-to-end and identify performance bottlenecks in complex architectures.

For monitoring system health and performance, you should collect counters, gauges, and histograms as standard metric types. These metrics provide actionable data trails that help track application behavior, measure performance, and maintain overall system observability.

Yes, you can trace requests across multiple microservices using distributed tracing. By instrumenting your code with OpenTelemetry, you create visual request flows that map out interactions across services, which is essential for debugging complex distributed systems.

You need structured logs instead of plain text because JSON formats make logs easy to parse and search. This structure creates actionable data trails, allowing you to quickly filter for specific error messages and correlate them with trace data during debugging.
