Flog is a Go CLI tool that generates fake log data in common formats such as Apache common/combined/error, RFC3164/RFC5424 syslog, and JSON. It supports output to stdout, files, or gzip archives with options for line counts, byte sizes, timestamps, splitting, and looping.

Use cases

• generate fake apache access logs for testing
• create sample syslog data for log pipeline testing
• generate log streams to test amazon kinesis
• produce large fake log files for load testing log parsers
• simulate continuous log output for monitoring demos
• generate json logs for testing log ingestion

When to choose

• you need realistic-looking log data in standard formats for testing
• you want a lightweight CLI or docker image to stream or generate logs on demand
• you need control over log volume, timing, splitting, and output format

When to avoid

• you need logs matching your application's custom format
• you need real production log data or anonymization of existing logs
• you need a library API rather than a command-line tool
