F5 BigIP v11 and Syslog over TCP

Hi All, I'm currently trying to configure syslog offloading and I'd like to know if there is a way through the UI (or tmsh) of setting the outbound transport to run over TCP. We don't use UDP in our environment, and I'd rather not have to manually edit the syslog-ng.conf file.

 

Ideas?

 

Thanks,

    Hi Josh,

    I think you'll need to use tmsh to import a custom syslog-ng configuration stanza. This default command doesn't seem to support a protocol property: 

    
modify /sys syslog remote-servers add { {host  remote-port }}

    Here's a solution from Alscion:

    tmsh modify sys syslog include "destination remote_server {tcp(\"10.1.0.100\" port (514));};filter f_alllogs {level (debug...emerg);};log {source(local);filter(f_alllogs);destination(remote_server);};"

    Thanks Aaron, this did the trick. I'm seeing logs on our log host for this unit now! I've opened a case with F5 support to see if this can be added as a UI option in a future release.

    Andrew, You could probably do something like this. Just double up the destination and log statements. (This is untested, fyi)

    tmsh modify sys syslog include "destination remote_server {tcp(\"10.1.0.100\" port (514));};filter f_alllogs {level (debug...emerg);};log {source(local);filter(f_alllogs);destination(remote_server);};destination remote_server2 {tcp(\"10.1.0.102\" port (514));};log {source(local);filter(f_alllogs);destination(remote_server2);};"
