Flog
A fake log generator for common log formats
...It was created to help developers and operators test systems that consume log data, such as log pipelines, SIEMs, or streaming platforms like Amazon Kinesis. Users can control the output by specifying the log format, output file path, log type (stdout, plain log file, or gzip-compressed file), and either the number of lines or the total byte size of logs to generate. Additional options let you simulate timing behavior by configuring creation intervals and generation delays, as well as splitting output into multiple files based on line count or file size. The tool can run in a loop to continuously emit logs until terminated, making it suitable for soak testing or stress testing log ingestion services.
