HTTP Profile troubleshoot

HTTP profile is enforcing RFC. How can I see logs of the exact violation and block? 

For example, if a RST sent due to RFC violation, I could activate BIG-IP system to log TCP RST packets (https://my.f5.com/manage/s/article/K13223), but then I only see a general error like "F5RST: Malformed HTTP header error" 

How can I log the actual error? For example: duplicate Transfer-Encoding header
