How to measure a Mobile app

Dear Experts,

I am very beginner to understand the Mobile infrastructure and Mobile app. Therefore please excuse if there are mistakes in asking the questions. As far as I know the Mobility users comes into our ECC system through Web dispatcher and Mobility Gateway. The version of Mobility Gateway and ECC system are

Mobility Gateway Netweaver 740 with UI* and IW* release of 100

ECC is ERP 6.0 EHP7

My Question is coming from measurement of apps. How do we measure the apps usage running under this environments. Is monitoring possible through ECC system if yes what is the report name

Else Will Google Analytics helps us to get this information.

Thanks
