-    - The `Compare Attribute` filter checks if the requested API can be handled by the API-Builder project.
-    _Right now, only the Traffic-Overview is implemented and can be handled by the API-Builder glue project. This will be extended soon!_
-    - Add a criterion: `http.request.path` is `/api/router/service/instance-1/ops/search` 
-    _The list of requests will be extended once the API-Builder project can serve more (e.g. the Request-Detail view). Right now, this is just hard coded for the topology we used for testing!_
+    - The `Compare Attribute` filter checks if the requested API can be handled by the API-Builder project.    
+    As a basis for decision-making a criteria for each endpoint needs to be added to the filter configuration.  
+    _At this point in time only two endpoints are supported by the API Builder based Traffic-Monitor API.  
+    The **search** endpoint which provides the data for the HTTP Traffic overview and the **circuitpath** endpoint which provides the data for the Filter Execution Path as part of the detailed view of a transaction. Currently the API Builder Project does not cover all endpoints to completely replace the existing Traffic Monitor API yet, but more endpoints will be added soon!_    
+    For search endpoint add: `http.request.path` matches regular expression `^\/api\/router\/service\/[A-Za-z0-9-.]+\/ops\/search$`  
+    For circuitpath endpoint add: `http.request.path` matches regular expression `^\/api\/router\/service\/[A-Za-z0-9-.]+\/ops\/stream\/[A-Za-z0-9]+\/[^\/]+\/circuitpath$`
