ASM Prevention for Slow HTTP Attacks

Hi Team, I have been reading the article https://support.f5.com/kb/en-us/solutions/public/14000/100/sol14199 after starting to notice these logs files on my F5. Now from the article these are slow HTTP connections being dropped but what I really want to know is:

 

• What is the threshold for these slow transactions dropping ?
• And can I find out any information on these dropped transactions ? If these are slow attacks, source IP and destination IP would be handy.

It all seems a bit "under the covers" in regards to what is happening here and I would love to find more information
