ASM URL based rate limitation rates.

Please explain diff parameters used in Anomaly detection in ASM.   TPS increased by, TPS reached and Min TPS threshold. Are these parameters dependent on each other? Is history data relevant here?...

Unfortunately no satisfactory answers. Only got response whatever information is there in ASM guidelines. They are seeing no unexpected behavior seen.

 

We had set below rates for URL based anomaly detection

 

TPS increased by 1000 % TPS reached 10 transactions per second Minimum TPS Threshold for detection 5 transactions per second

 

Queries are - 1) If requests are coming at 9 or 10 TPS rate, will those get throttled? 2) During our testing we pumped the request at 12 TPS rate, shouldn't F5 reject 2 req/Sec with above settings? 3) Tests shows if 12 TPS rate traffic is coming, 50% of requests get throttled? aren't these numbers crazy? Shouldn't F5 reject only 16% of traffic here?
