Entering a permanent license key

If a permanent license key has already been installed on your appliance skip this step of the Setup Wizard and proceed directly to the next step. If your appliance has only a temporary key the Appliance License page of the Setup Wizard appears as shown in the following illustration.

To obtain a permanent license key, you need to provide Technical Support with the Host Id as shown on this page. Once you receive the license key paste it into the License Key field and click Next to continue.

Configuring the Appliance Type

The next Wizard Setup step is the Type page.

Figure 8. Type page

The appliance must be configured either as a stand-alone machine, or as part of a multi-appliance cluster. Stand-alone appliances do not communicate with other appliances, whereas appliances that are part of a cluster make use of a portal to aggregate metrics from probes, and present a unified view of the cluster of appliances. For more information, see Multi-appliance clusters.

You can configure your appliance for one of three distinct roles. First, it can function as a portal that provides a unified database and configuration repository for a cluster of appliances. Portals provide a unified view of the metrics collected by multiple probes, they do not monitor network traffic. Second, it can function as a monitoring probe in a multi-appliance cluster. Probes monitor network traffic based on the configuration specified on the portal, and transmit all of their collected metrics to the portal. Third, it can function as a stand-alone monitor. Stand-alone monitor network traffic and save collected metrics into a database on the same appliance. They do not communicate with other appliances.

When you change the appliance type using this page, a pop up window appears informing you that the process may take a few minutes.

If you are installing a single appliance on your site, or one of multiple appliances that are not going to share metric data, select Stand Alone Monitor, then click Next to continue configuring the appliance.

The following procedure sets up the appliance to function as a Portal.

Select the Encrypt using SSL check box if you want the data communications between the portal and probes to be encrypted using SSL.
Select the Compress to minimize bandwidth check box if you want network communication between the probes and portals to use data compression.
Click Next to move to the next step of the Wizard.

The following procedure sets up the appliance to function as a Probe.

Click Next to move to the next step of the Wizard.

The server addition and discovery process found in the Setup Wizard is identical to configuration functionality that is used after installation. To further refine your server list, see Managing monitored servers.

Designating Time Servers

The Time Servers page allows you to identify one or more Network Time Protocol (NTP) servers. Setting NTP servers ensures accurate synchronization of the appliance’s internal clock to the correct time.

Type up to three NTP server IP addresses in the Time Server (#1, #2, #3) boxes on this page. Click Apply when you have finished configuring NTP server information.

If configuring a portal, the Setup Wizard is complete at this point. Proceed to Completing the Setup Wizard.

Configuring protocols

The Protocols page of the Setup Wizard enables you to specify which protocols and ports you would like the appliance to monitor. The appliances provides detailed metrics for HTTP and a standard set of metrics for all other TCP-based protocols.

Figure 10. Protocols page

HTTP on ports 80 and 8080 and HTTPS on port 443 are automatically configured as default protocols. If your site uses other ports, modify the list of ports for each protocol on this page.

If your site uses protocols, other than HTTP and HTTPS, click Add a Protocol to define the protocol and the ports it uses. After the protocols and port numbers are configured to match those used by your site, click the Next button to advance to the next step of the Setup Wizard.
