    I believe you can use the following sample code.

    Just cut out information you don't want to log

     

     

    I hope this helps

    In addition to CB's useful suggestion, you can also use the 'log ' option in 9.4 and higher to bypass syslog-ng and send syslog messages directly to a remote syslog server:

     

     

    iRules Update: The "log" command gets new options

    And here is another Codeshare example which logs IP:port details for TCP/HTTP/UDP VIPs:
