Show HN: Dllog – Replay debug logs when an operation fails
TL;DR
Dllog is a tool designed to enhance debugging by replaying logs of operations that fail, providing context with original timestamps. It operates independently of existing logging libraries, offering a focused view of errors without cluttering successful operation logs.
✦ Why It Matters
Integrate dllog into your debugging workflow to streamline error analysis and improve troubleshooting efficiency.
Key Takeaways
- Integrate dllog with your existing logging library for enhanced error reporting.
- Use the Middleware function to automatically manage logging scopes in HTTP servers.
- Leverage the Scope and Trip functions to control when debug logs are emitted.
- Monitor performance impacts, as dllog has minimal overhead for successful operations.
How It Works
Dllog buffers debug logs in a ring structure specific to each operation. When an operation fails, it replays the buffered debug logs, providing context for the error while discarding them for successful operations.
This mechanism allows developers to maintain clean logs while still having access to detailed information when needed.
