Viewing Performance Management Statistics

 

The following topics show how to view the performance statistics for point-to-point and VPLS services:

Viewing Statistics for Point-to-Point Service

In the Network Activate task pane, select Service Provisioning > Manage Services.

To view the statistics for the point-to-point service:

  1. Right-click a point-to-point service and select View PM Statistics.

    Note

    The View PM Statistics action is enabled only after performing the Start PM Statistics.

  2. View and analyze the respective graph.

    The Delay Measurement graph displays a real-time linear plot of delay value with respect to the time. The x-axis represents the time and the y-axis represent frame delay in microseconds.

    The Delay Variation graph displays the difference between the consecutive frame delay values. The x-axis represents the time and the y-axis represent delay variation in microseconds.

    If the delay measurement is one-way, the following graph is displayed.

    If the delay measurement is two-way, the following graph is displayed.

    The Loss tab is displayed only if you have selected the Loss check box. It displays two real-time linear plots: Near End (CIR) and Far End (CIR). The three parameters in each graph plot are average case, best case, and worst case of frame-loss.

    The graph is plotted in real-time. By default, the total time duration is ten minutes. If the duration of statistics collection exceeds ten minutes, the graph scrolls and shows the data of latest ten minutes. To stop the data collection, click Stop.

Viewing Statistics for VPLS Service

In the Network Activate task pane, select Service Provisioning > Manage Services.

To view the statistics for the VPLS Service:

  1. Right-click a VPLS service and select View PM Statistics. The Monitor Performance Statistics page appears.

    Note

    The View PM Statistics action is enabled only after performing the Start PM Statistics.

  2. View and analyze the graphs.

    The Delay Measurement graph displays a real-time linear plot of delay value with respect to the time. The x-axis represents the time and the y-axis represent frame delay in microseconds.

    The Delay Variation graph displays the difference between the consecutive frame delay values. The x-axis represents the time and the y-axis represent delay variation in microseconds.

    By default, the total time duration is ten minutes. If the duration of statistics collection exceeds ten minutes, the graph scrolls and shows the data of latest ten minutes. To stop the data collection, click Stop.
