Rotating Domain Manager log files

One of the difficulties in parsing Domain Manager log files is dealing with log file rotation. By their nature, Domain Manager log files grow over time. Most system administrators set up periodic jobs to remove or rename the log files to avoid consuming too much disk space. The file tail front end periodically checks if the file has been rotated. If so, the file is closed and reopened. The file is then read from the beginning. All entries in the newly opened file are fed into the rule set.
