Completing the Setup Wizard

The final page of the Setup Wizard summarizes the configuration choices made in previous steps, and asks that you confirm them.

Review all the configuration settings. It you need to return to any point in the Setup Wizard to make modifications, click the Jump to Page links to move to specific pages, or use the Setup Wizard Back button to review pages in reverse chronological order.

When you are satisfied with the configuration settings, click Finished to complete the Setup Wizard.

After clicking Finished, you are taken to the home page. The appliance begins to monitor traffic and metrics begin to appear within 10 minutes.

TIP: After the appliance is deployed, if you encounter data collection or communication problems, see Troubleshooting the appliance for help. The steps outlined in the Troubleshooting chapter help you to pinpoint the source of these problems.

Maintaining the appliance

As a best practice, it is recommended that you reboot each appliance at least once every 90 days. This operation can be performed through the console program (for details, see System restart).

Rebooting the appliance allows the system to run the standard file system maintenance utilities (fsck and xfsrepair) during the boot-up sequence. This helps to avoid file system inconsistency errors that periodically arise in the normal course of operations. Failing to run these system maintenance utilities on a regular basis may result in the need for manual disk repairs that could involve booting the system from a CD.
