A dirty log in a system is a common precursor to trouble.

Excessive logging can be as detrimental as no logging at all.

When your system is in production, monitoring is crucial.

Logs are often part of this monitoring, and they serve as an early warning system for issues.

Ensuring your error log contains only critical issues can save you from being woken up for minor hiccups.

Distributed systems introduce complexity due to external dependencies.

Logging policies should consider how to handle failures in such scenarios, especially if failures are frequent.

In distributed systems, the messages at lower priority levels often indicate system health.

Aim for an INFO-level log message for each significant application event to maintain clarity.

A cluttered log indicates potential production control challenges.

Expecting a clean error log simplifies troubleshooting when issues arise.

Effective log management is essential for system health, ensuring that critical problems are brought to your attention.
