The Service Manager purges log events from the log directory according to the purge properties. The default value for preserving logs is 30 days and the default maximum size for log event files is 200 MB.
When the number of days or the size of the log directory exceeds the limit, the Log Manager deletes the log event files, starting with the oldest log events. The Log Manager periodically verifies the purge options and purges log events. The Log Manager does not purge the current day log event files and folder.
