Did you manage to get any update or resolution on this query. As i can see we have two options that
1. Using PA and APM KM
2. Using API's
third I'm trying to link up the APM DB with the SMART Reporting, but, i didn't fine any support document for this just giving a try on that.
Meanwhile if you find any way please share with me. I've stucked here in this point at implementation.
