How to troubleshoot orm queries interfering with other applications
I would strongly suggest metadata in the connection in order to trace back to the application.  In the connection string, there is an Application Name.  There is also session data which can be used in the form of CONTEXT_INFO

Of course all this requires application changes, but it is good for tracing and auditing in general, so baking it in from the beginning is really useful.
