FAQ: Processing zipped, gzipped, or bzipped Log Data
Can Sawmill process ZIPped, gzipped, or bzipped log data?
Yes, all three.
Yes. Any files that end with a .gz, .zip, .bz, or .bz2 will be treated as compressed files by Sawmill. It will uncompress them "on the fly" (not modifying the original file and not creating any new files), and process their uncompressed data the same way it reads normal log files.
