Right-clicking on the graph produces a pop-up menu, on which you can select the Auto Range Graph Axes menu option. This option restores the graph to its original unzoomed state.

Poll Rates

When the Detailed Graph dialog box is displayed for any monitor on a particular device or link 3Com Network Director increases the poll rate for the active monitors of that device or link to every 10 seconds in order to provide you with more detailed graphs.The poll rate for the active monitors of the device or link revert to their configured settings when you close the Detailed Graph dialog box.

If you close the Detailed Graph dialog box for a device or link and still have the Live Graphs window up for that device or link, or vice versa, then 3Com Network Director will continue to use the 10 second polling rate for all of the active monitors for that device or link.

Configuration	The following section describes how to configure the monitoring system
	so that it provides the data that you require in managing your network.

Starting and Before 3Com Network Director can generate events for devices in your Stopping Monitoring network you must first start monitoring on those devices.This can be

performed automatically from the Network Discovery Wizard.

See“Specifying Monitoring Mode in the Discovery Wizard” on page 302 for more information.However, you may wish to modify the set of monitored devices and links to focus only on specific items in your network, you may wish to exclude specific sections of the network from monitoring, or you may wish to reduce the amount of network traffic generated by 3Com Network Director’ active monitors.

To start monitoring on a set of devices and links, select the items that you want to start monitoring and select either Monitoring > Start Monitoring from the main menu or Start Monitoring from the right-click menu.If your selection includes a subnet or device group then 3Com Network Director will recursively start monitoring on all core devices and links in that group that are not visible at a higher level in the map.

3Com Network Director will automatically start monitoring for an unmonitored device or link if you launch the Live Graphs window for it.
