I have been asked for a list of all of the KPI's that dynatrace can collect from different technologies... I.E. java - Garbage collection time, total collection time... Linux - Host memory, Host CPU etc etc.
I have found that list here -- at the bottom of this page, follow both the "Click to view the list of built-in Managed timeseries" and "Click to view the list of plugin Managed timeseries" links.
