For example, consider the appearance and function of Bandwidth Utilization
when monitoring a switch.
Figure 9: Switch Bandwidth Utilization
Compare that to the Bandwidth Utilization window on page 20. Instead of
measuring the gross network bandwidth utilization, Observer is now able to
give the network administrator an ongoing picture of the bandwidth
utilization of the switch on a port-by-port basis and an aggregate “switch
throughput.”
To enable the local probe to monitor a switch:
1. Select
Options > Selected Probe or SNMP Device Properties .
2. Click the S WITCHED O BSERVER option button.
3. Click O K in response to the message. This displays the switch dashboard.
Supply the required information, including:
• IP address of the switch
• Switch manufacturer
• Administrative password for the switch (or write community name)
4. Select the type of management you want—looping or static monitoring of
selected ports.
5. Click the icon on the Device Properties toolbar to start monitoring the
switch.
You must be connected to the switch to monitor.
