Harvest Grafana: any idea/solution to get perfadvisor data from OCUM (OCUM 5.x) to Graphite

[#1]

we do have some 7 Mode Systems integrated in OCUM 5 and Perfadvisor. To get a complete view to the data of all filer, we thought to import Perfadvisor data for 7-Mode Systems (history datasource).

It is not allowed to implement the 7-Mode Systems direktly .
