| 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 retrieves the values |
| from the database and displays them in a graphical user interface. |
| |
| Performance history values |
| -------------------------- |
| |
| After selecting a connected PNF supporting ONF-TR-532 and a physical |
| interface, the application collects the received and centralized stored |
| performance values for this interface. |
| |
| The values are visualized using two views: a line chart and a table, |
| with the chart always shown first. To switch between them, toggle |
| buttons can be used. The chart view offers a filter to quickly limit the |
| shown values. To keep both views in sync, the filters of the chart and |
| the table are connected. If one view is filtered, the other one gets |
| updated in the background. |
