Log when voucher is used

[luis.souza]

How can I check when a voucher is used?

[Gertjan]

What about Status => Captive Portal ?

Thank you for your reply Certjan,

Yes, in this page I can see the voucher currently in use and voucher status (good for XXX minutes or expired), but I need view when a expired voucher was used used for audit.

Status>System logs, Portal Auth. Log it to a syslog server if you want to retain it long-term.

Thank you cmb, I installed the syslog-ng package to retain and rotate this logs.
