auditlogviewer

Audit log files directory path is a required argument.
usage: auditlogviewer <path1> [<path2>...<pathN>] [options]
--
View the audit log contents in human readable format
--
Options are:
-f,--follow       Upon reaching the end of the log continue indefinitely
                  waiting for more records
-h,--help         display this help message
-r,--roll_cycle   How often to roll the log file was rolled. May be
                  necessary for Chronicle to correctly parse file names. (MINUTELY, HOURLY,
                  DAILY). Default HOURLY.
