Performance
===========

Performance Monitoring values measured by the devices are necessary to
analyze and optimize the network. Therefore the application
automatically retrieves all historical performance values from the
devices and stores them in a database. The client part just retrieves
the values from the database and displays them in graphical user
interface.

Performance history values
--------------------------

After selection of a connected PNF supporting ONF-TR-532 and an physical
interface, the application collects the received and centralized stored
performance values for this interface and displays them in table views.
