We have IIS boxes that use ARR and some rules to route calls to some sites on the same box. These sites have applications that have their own NewRelic IDs and the newrelic integration there is working fine.
Problem is when, for some reason, an app pool is hanging. The app does not receive the request, so there is nothing in APM for it. But we know that the request had to go through ARR. So we would like to put monitoring on the ARR to look for hanging requests passing through the root site by ARR.
Could someone please point me to the documentation on how to monitor requests passing through ARR with NewRelic?
