Viewing router utilization statistics
Router Observer is suitable for searching for failing or over-stressed routers, and it can determine whether the source of demanding packets is incoming or outgoing (or both).
Classic mode must be enabled.
The Router Observer tool, which allows you to monitor one or more routers’ utilization rates. Observation is done passively; the router is not performing extra work.
On the Classic tab, in the Statistics group, click Router Observer.
Figure 6: Setting the known speed of a router
The top status bar shows router speed and IP address. In Graph view, dials show packets per second, bytes per second, and the current utilization. When you receive user complaints that the network is slow, check the 1 minute, 1 hour, and total bandwidth utilization averages. You can tell whether a bandwidth problem is temporary or persistent. Each listing also shows values by direction (in or out of the router).
Router Observer can be configured to show additional routers—you are not limited to viewing just one router. So, to view the real-time statistics of routers in bulk, simply configure more routers in Router Observer.
To do this, right-click the row of empty tabs near the lower, leftmost portion of the Router Observer window, and click Create Router Observer Window.
At least one router must be configured before Router Observer can be activated. To configure a router, click the Settings button and select an address to monitor.
Note: Be sure to select the address of a port, on your router, that is visible to Observer . For example, no results are seen by selecting an outside interface, as the MAC address is not visible.
You must specify the router speed before continuing. Type the speed and click OK. Now click Start to activate. As always, you can change your layout by clicking View and selecting something else.
Results can be saved in a comma delimited file using File > Save > Save Data.
