This page summarizes the criteria that you can use for creating custom match and exclude rules for each entry point type.

The criteria are the same for custom match and exclude rules.

If you disable automatic detection for an entry point type and then apply custom match rules, the agent discovers only requests defined by those match rules. For example, if you have a PHP MVC custom match rule that matches on “Action contains search”, and another rule that matches on "Action contains view", requests that contain "search" or "view" are the only MVC transactions that the agent detects.

On the other hand, if you do not disable automatic detection and you apply a custom match rule “Action contains search”, all the requests that match that criterion are grouped together as a single "search" transaction and then any other requests (those that do not contain “search” ) are discovered using automatic detection.
