Lumberjack is a Go package for writing logs to rolling files, handling rotation by size, age, and backup count. It is a pluggable io.Writer component that works with any logging library, including the standard library's log package.
Use cases
- rotate log files by size in a Go application
- limit disk usage by deleting old log backups
- compress rotated log files
- plug rolling file output into zap or standard log
- write logs to files with automatic rotation
When to choose
- you need log file rotation in a Go program
- you want a simple io.Writer-based rolling logger
- you need size/age/backup retention policies for logs
When to avoid
- you need a full logging framework with formatting and levels
- multiple processes write to the same log files
- you need centralized or network log shipping
