How to find out what request is put by the IIS server?

Question

IIS

Rarely, once a day, the processor rises to 99% (Application Pool).
It's most likely a script.
How to find out which script and with what parameters?
Where is everything logged? Does it need to be included somewhere.
IIS 10 Windows Server Standard 2016

Answer 1

By default, in IIS for the Application Pool, the "pool recycle" parameter is set to 1740 minutes (29 hours),
perhaps this restart loads the percent.

Answer 2

Perhaps it will come in handy for someone, I also had an incomprehensible situation when IIS loaded the percentage up to 100% and very often, I took from the pool that is being loaded, I changed the "Maximum number of worker processes" setting from 0 to 5 and the problem disappeared. 0 means IIS itself launches as much as needed, in my case it launched only 2 and they ate 15 gigs of memory, when I did 5 everything became much faster to work.
