Two grb_rs.cnf configuration properties control the rotation of log files:
-
LOGFILE_MAX_SIZEis the maximum size in megabytes of the log file before it gets rotated. The default is 500 megabytes. -
LOGFILE_MAX_AGEis the maximum number of days to retain old log files based on the timestamp encoded in their filename. Note that a day is defined as 24 hours and may not exactly correspond to calendar days due to daylight savings, leap seconds, etc. The default is 5 days.
Example
- Set the limit to 1 MB via
LOGFILE_MAX_SIZE=1. - Store the log to
grb.log.
$ ls -lia *.log

The most recent log will always be in grb.log. When the grb.log file reaches the maximum size, it will be moved to a name with a timestamp with the same prefix, and a new and empty grb.log is then used. Finally, the maximum age property controls how long to keep these log files with timestamps. When a new file is needed, and there is a file that is older than the maximum age, that old file will be deleted.
