Server Log Files

The log file of the AAA server contains all the information concerning the functioning of the server such as: start/stop of the server, all of the RADIUS requests, and some internal events. The data is automatically stored each day in a different file. They are available as long as the corresponding files are still on the disk.

/var/opt/aaa/logs/logfile: the server log file
/var/opt/aaa/logs/logfile.yyyymmdd: compressed daily or weekly log files
