Accessing the Central Manager

From a secure web browser, log in to WAAS Central Manager using either its hostname or IP address on port 8443 as follows:

https://CM-Host-Name_or_IP Address:8443

You must have proper username and password credentials to log in to WAAS Central Manager.

You initially open to a view of the WAAS System Dashboard, from which you can monitor your WAAS system. When you choose a device from the Devices menu, you move to the a view of the Device Dashboard, from which you can monitor specific device activity and performance.

Using the WAAS System Dashboard

The WAAS Central Manager GUI allows you to view general and detailed information about your WAAS network from the System Dashboard window, which is shown in Figure 1-1.

Figure 1-1 System Dashboard Window

The dashboard provides a snapshot of your WAAS network. You can use the menu at the top of the dashboard window to view more detailed information about your devices, and to configure, monitor, and administer your network.

The Alarms section of the dashboard, in the gray status bar area at the bottom right of the window, provides instant access to any alarms, as described in the "Viewing Alarms" section.

Viewing Alarms

The Alarms panel at the bottom right side of the Central Manager window provides a near real-time view of incoming alarms and refreshes every two minutes to reflect updates to the system alarm database. The alarms are classified as Critical, Major, or Minor depending on the impact the issue might have upon the WAAS environment. You can click Alarms to display the panel, which is shown in Figure 1-2.

Figure 1-2 Alarms Panel

The Alarms panel contains a filtering option that allows you to control which alarms are shown in the panel. You can check the check box next to an alarm name, and then click the Acknowledge taskbar icon to enter any comments you have about the alarm.

For a complete list of alarm conditions, see the Alarm Book located in the WAAS Software Download area on Cisco.com.

Viewing Device Information

The WAAS Central Manager GUI allows you to view basic and detailed information about a device from the following two windows:

Devices Window—Displays a list of all the devices in your WAAS network with basic information about each device such as the device status and the current software version installed on the device.

Device Dashboard Window—Displays detailed information about a specific device, and provides menu access to reports and other information about the device.

Devices Window

The Devices window displays a list of all the devices in your WAAS network with basic information about each device such as the device status and the current software version installed on the device. You can use either of these actions to display the Devices window:

Click the Devices menu in the Central Manager window.

Roll over the Devices menu in the Central Manager window and click All Devices.

An example of the Devices window is shown in Figure 1-3.
