Bandwidth Gauges are simple to set up. As long as you have enabled SNMP communication on your devices, and your devices support MIB-II, you can monitor bandwidth usage with the Bandwidth Gauges tool. The number of gauges is governed by the memory of the Toolset computer. Real time utilization is based on the number of octets transmitted or received through an interface over the last few seconds. Bandwidth gauge polls the remote interface about every fifteen (15) seconds by default and calculates average bits per second since the most recent poll. You can select any interface or sub-interface of a frame relay to monitor.
- Click Gauges > New Gauge.
- Specify the device IP address or host name.
- Select to use a community string or SNMPv3 credentials.
To test the credentials, click Test.
Specify if you want to store the credentials in the shared credentials database when prompted.
- Select discovered interfaces or ports, and then click Next.
- Check that Adjust automatically-discovered speed is correct, or specify your own speed.
Different speeds can be specified for transmit and receive. The tool uses the port speeds to calculate percent utilization of the interface and define the upper scale of the gauge.
- Select 64-bit or 32-bit traffic counters.
- Click Finish.
The gauge measures a baseline, and then immediately start monitoring usage.
