The System Administration & Diagnostics application maintains a set of log files for each application instance. The log files are names as follows:
dashMMddyyyy_hhmmssfff_lognum.log
MMddyyyy_hhmmssfff represents the timestamp of when the application instance was started.
lognum represents the log number for this log file. The numbers start at 0001 and increment for each log file. A new log file is created after the previous file reaches one megabyte in size.
