#login on-success log

The problem with this is that it logs to the buffer which will eventually overwrite. so its suggested to have a syslog server. And this line doesn't work if you're authenticating to a RADIUS or TACACS server, it only works if you're using local authentication.

configure the tacacs/syslog server to get all the required information.
