Nice to know, application detection rule failes

henk_stobbe — Sat, 19 Feb 2022 10:30:16 GMT

Hello,

In below request header Dynatrace has detected that the request comes from domain localhost:8085

This is a intermediate service that gets its request from the actual server

Easy mistake to make is using the original server domain, but that will not work! You need to use the localhost:8085

If you start with the "My web application" the top included domain will show the referer domain from the Request Header not the localhost:8085 you need. So creating or adding to an application here will not work!

When you have created a detection rule with the localhost:8085 from scratch, in that application newly created application the top included domain will also contain the referer domain, but the reqeust will start show,

Checking backtrace for the frontend services also helps in some cases.

Hi @Ingrida , you can try check for the frontend service backtrace, then on "Calls from unknow hosts" you may see the reffering pages that makes calls to the service.

Try to set up rules for these pages and see.
