5.14.1 Set Traffic Data Collection to Manual Mode in Large Networks
The traffic monitoring capabilities of the HP Toptools Traffic Monitor application can require a lot of system
resources. Therefore, in large network environments, it is suggested that you manually select the points at
which you would like to collect traffic data. Usually, you will want to collect traffic data on your network
backbone segments and on segments with heavily utilized servers.
Traffic Monitor can use the HP X-RMON functionality built into HP Procurve and HP Advancestack and even
HP Ethertwist network devices to provide detailed information on who is using network segments. It also uses
standard traffic counters to provide basic traffic levels on network segments. Traffic Monitor can realistically
monitor up to 200 network segments using the HP X-RMON technology. It can monitor up to 1800 additional
segments using standard traffic counters. You should use the following instructions to turn on Manual traffic
data collection and configure which network segments will be monitored with HP X-RMON and which
additional segments will be monitored using standard traffic counters.
• Go to the Toptools Home page by selecting Tools -> HP Toptools ->Toptools Home from the OpenView
NNM menu bar
• On the Toptools Home page, select Performance ->Traffic Data Collector Settings
• On the Performance – Traffic Data Collector Settings page select the “User Selected Switch and Hub
Ports (Manual)” setting
• Use the Add Device(s) button to add the devices on which you would like to collect Traffic Data
• On each device, select the ports on which you would like to collect Traffic Data by expanding the device
and then selecting either the Traffic Stats or the HP X-RMON check box for the desired ports.
• Click on Restart Collector. The Traffic Data Collector starts with your changes.
