Is there a way to make the number of lines shown with show ap debug auth-trace-buf higher?

Or can i somehow log these lines to an external server? I have set all categories to debug for syslog, but don't see it.

Anything else possible?

It is a useful command, but in a busy enviroment it becomes difficult to get the transaction from the client you are looking for.

You cannot limit the number of lines, or send it to syslog but if you turn on user debug only for a few specific clients, the output will only be limited to those clients:

(Aruba7005-US) #configure t
Enter Configuration commands, one per line. End with CNTL/Z

(Aruba7005-US) (config) #logging level debugging user-debug de:ad:be:ef:ca:fe
(Aruba7005-US) (config) #show debug

DEBUG LEVELS
------------
Facility    Level      Debug Value        Sub Category  Process
--------    -----      -----------        ------------  -------
user-debug  debugging  de:ad:be:ef:ca:fe  N/A           N/A

(Aruba7005-US) (config) #exit
(Aruba7005-US) #show auth-tracebuf 

Warning: user-debug is enabled on one or more specific MAC addresses;
         only those MAC addresses appear in the trace buffer.

You would then use something like airrecorder to periodically collect the output of show auth-tracebuf.

thanks cjoseph, this is about Instant so i believe the logging level user-debug isn't possible? it just collects it for everyone?

ill look into the airrecorder, sounds useful.

Correct, on instant the auth-tracebuf shows all devices.  You would use airrecorder to script running that command on the IAP  at intervals to get the whole picture.
