Maximum message size using logging profiles

Hey Ian!

 

 

The maximum possible size for remote logging messages is 2048 bytes when using the RFC 3195 protocol. You're correct that the remote logging for ASM is controlled by ASM rather than the system's normal syslog configuration.

 

 

I believe that the size limitations are imposed by the protocol - at least the non 3195 limitations certainly are. As I recall the RFC 3195 update was ambiguous as to size restrictions, but many implementations will still only read 2048 bytes. If you have a case where your servers will definitely accept more than this, then it is worth opening a case with F5 Networks Support to request an enhancement to the remote logging for cases in which you *know* you can handle more than 2k.

 

 

Cheers!
