Logging is a critical component for maintaining system integrity and performance in complex IT environments. Effective logging practices streamline troubleshooting, enhance performance monitoring, and bolster security by enabling the detection of anomalies and unauthorized access. The article outlines ten best practices for logging, emphasizing the importance of structured logs, consolidation of log entries, and the use of unique identifiers to facilitate debugging. It advocates for standardizing log formats, avoiding the logging of sensitive data, and treating logs as actionable data. A centralized logging management system is recommended to aggregate logs from various services, improving analysis and correlation. Additionally, configuring log retention policies, setting up alerts for critical issues, and documenting logging practices are essential for maintaining clarity and compliance. Honeycomb, an observability platform, is highlighted for its capabilities in log analysis, allowing users to visualize and query logs effectively, thus enhancing the overall logging strategy. By implementing these best practices, engineers can ensure their logging efforts are efficient, actionable, and scalable, ultimately leading to improved system observability and performance.

Structured logs are the way to start
Structured logs are crucial for system insight, aiding search and aggregation. Despite storage challenges, prioritizing indexing and retention strategies is key. Valuable lessons can be gleaned from email for software processes.
Bad habits that stop engineering teams from high-performance
Engineering teams face hindering bad habits affecting performance. Importance of observability in software development stressed, including Elastic's OpenTelemetry role. CI/CD practices, cloud-native tech updates, data management solutions, mobile testing advancements, API tools, DevSecOps, and team culture discussed.
Plaintext is not a great format for (system) logs
Using plain text for system logs poses challenges due to rich metadata. Approaches include augmenting logs with metadata, storing it separately, or discarding it. Tools can help manage metadata, making logs more structured than plain text. JSON, though text-based, may not be plain text.
OpenTelemetry Tracing in < 200 lines of code
OpenTelemetry tracing simplifies to structured logging and context propagation, using spans for metadata. It supports distributed tracing via HTTP headers and requires instrumentation to capture trace data for monitoring.
There's always an events table (2022)
The article highlights the challenges of maintaining large event tables in SaaS products, emphasizing the need for effective cleanup strategies and proactive data management to enhance performance and prevent issues.
2 commentsThe main exception I can think of is legacy systems that can't really be retrofitted with tracing. In which case you're probably not in a position to implement logging best practices either. I suppose audit is another exception, where you want a longer-term record of what's happened, but even there I think traces get you the much better story of what happened across your environment and you just need a better archival storage solution for them.
