In past logs (firewall log in GUI and syslog messages), ICMP related log entries include the ICMP Type and Code name. For example, Echo, Echo-Reply, Unreachable, etc. That information is now missing from the log messages, possibly since 18.1 - not sure exactly when this information disappeared. Here is an example syslog message.
firewall.localdomain.com filterlog[72261]: 66,,,0,vtnet1,match,pass,in,4,0x0,,31,0,0,none,1,icmp,84,54.72.63.208,10.1.1.183,datalength=64
Any way to add that information back to the log message?
