Retrieval of EWA relevant information in machine readable form

Hi!

I use SAP Solution Manager (SPS 16) with a lot of satellite SAP systems and get each week a valid EWA report.

Now I would like to get a automated retrieval of EWA data in machine readable form.

So it should not be a EWA report, but e.g. a XML file with all the relevant information (e.g. parameters, performance, etc.)

Question

What are the technical steps to do this?

How can I retrieve such information? (interface, tcode, report)

Thank you very much

Jürgen
