Monitoring ATM-VLAN Performance

This chapter describes AtmDirector features for monitoring and graphically displaying ATM-VLAN performance information for client and broadcast server components.

Graphing Client Performance Information

The Client Performance window provides real-time graphs of the traffic on a selected client.

To display the graphical display of client performance information, follow these steps:

Step 1 From the AtmDirector main window, double-click on the name of an ATM-VLAN to display the ATM-VLAN topology.

Step 2 Select a client from the ATM-VLAN topology map.

Step 3 Select Performance>Client Performance.

The Client Performance window opens (Figure 11-1).

Figure 11-1: Client Performance Window

When the window opens, sampling begins and continues at the specified sampling interval. The default sampling interval is 10 seconds. The numbers on the y axis of each graph represent units of the sampling interval. The numbers on the x axis represent the absolute count of units detected. The follow data types are plotted:

Data Frames--unicast received and sent by the client and frames received and sent by the client in error
Data Octets--data octets received and sent by the client
Control Frames--control frames received and sent by the client
ARP Requests/Replies--ARP requests and replies received and sent by the client

Step 4 Click Print to print a copy of the screen.

Step 5 Click Close to stop sampling and close the window.

Graphing Broadcast Server Performance Information

The Broadcast Server Performance window provides real-time graphs of the broadcast server traffic.

To display the graphs of broadcast server performance information, follow these steps:

Step 1 From the AtmDirector main window, double-click on the name of an ATM-VLAN to display the ATM-VLAN topology.

Step 2 Select a broadcast server from the ATM-VLAN topology map.

Step 3 Select Performance>Broadcast Server Performance.

The Broadcast Server Performance window opens (Figure 11-2).

Outgoing Frames--unicast and non-unicast frames sent by the broadcast server. Non-unicast frames include multicast and broadcast frames. Under normal conditions, the broadcast server should transmit more non-unicast data than unicast data.
Outgoing Octets--data octets by the broadcast server.

Step 4 Click Print to print a copy of the screen.

Step 5 Click Close to stop sampling and close the window.
