Use case help

Hi anyone I need help with use case.On my school project I need to write use case scenario:customer will have option too measure some data on wcf service.Problem is that I don’t know how to group use cases.Can I have customer as primary actor and 4 use cases
with names perform service measurement, perform endpoint measurement,perform contract measurement and perform operation measurement or should I name it more specific like one use case is name of the measurement operation that will be perform.
Question is if I do that on that other way I will have about 150 use cases for every single measure that I can perform on wcf.
Thanks in advance

Keep use cases generic and write anything specific within the use case description if you really need to. Your mention of having four use cases seems valid to me although I don’t completely understand the problem domain.
