Product Feature: General
I have specified below the steps to set up the request logging via Enterprise Manager.
You will need to perform the following for each service:
1. Right click the service and navigate to Services > Events > Settings
2. Specify the location of this new log on this page.
3. Scroll down and select "SOAP.Request" to log requests and select the "Alerts" check-box if you would like active notifications on any type of logging from this service.
Unfortunately, Envinsa doesn't provide the functionality to look up the source of the requests natively.
