I'm having a bit of a problem fully grasping how to search up rules that have been fired.....

2013-05-07T10:14:05-07:00 firewall snort[62223]: [120:8:1] (http_inspect) INVALID CONTENT-LENGTH OR CHUNK SIZE

Ok so what I understand from the log is that rule 120 fired. Either I need some caffeine or it's a horrible Tuesday 
for me to comprehend this, but I'm just not getting it. The instructions on how to search for the group id and the 
sid for some reason are not sticking. Can someone dumb this down for me....I'm gonna run out and get a pop and 
hopefully come back to someone who has awesomely helped me out.


Basically I want to be able to search for explanations on whatever event happens so I can determine if I need to take 
action or not.
