Fedora Log Files
This document describes the guidelines for log file(s), for use and inclusion in Fedora packages.
Log Files on the filesystem
Packages with log files must reside in their own directory under /var/log which must be named /var/log/$package_name
Each log file in that directory must end with .log filename.
Each package that ships log files must also ship a logrotation file that rotates the log file(s).

Logrotate file
Example logrotate file without daemon reload
/var/log/example/*log {
missingok # If the log file is missing, go on to the next one without issuing an error message
notifempty # Don't do any rotation if the logfile is empty
compress # Compress older files with gzip
delaycompress # Don't compress yesterdays files
sharedscripts # Scripts are only run once for all files in directory
}
Example logrotate file with user creation but without daemon reload
/var/log/example/*log {
missingok # If the log file is missing, go on to the next one without issuing an error message
notifempty # Don't do any rotation if the logfile is empty
compress # Compress older files with gzip
delaycompress # Don't compress yesterdays files
create 640 owner group # Set create mode immediately after rotation
sharedscripts # Scripts are only run once for all files in directory
}
Example logrotate file with user creation and with daemon reload
