How to show the auditing process of objects during policy auditing

L0 Member

Hi Everyone,

I'm a new member FW Palo Alto,
Currently, I have done a dump of the rule checking process, but I cannot show the process of checking each object against the rules in the firewall, so that I can clearly see the rule checking and the matching of objects before and determines which rule will be selected to handle traffic.
For checkpoint I can show this checking process, but palo alto I can't show it, below is the dump information that I performed on my lab system
