Configuring the Services

Services are configured on a per-server, per-interface basis - every server/interface combination must have a service defined for it.

1. In the main NetScaler screen, click Services to display the Services pane.

   

2. Click Add to create a new load balancing service. The Load Balancing Service Pane appears.

   

3. In the Service Name field, type the service name. A useful naming convention is to include the name of the server and the port in the service name. For example, if your server is named CWE-2008 and the port for the TAP interface is 3100, the service name could be CWE-2008-TAP3100.
4. Select Existing Server.
5. From the Server dropdown list, select the server that you want to associate with this service (such as CWE-2008).
6. In the Protocol dropdown list, select TCP.
7. In the Port field, type the port for the TAP interface (such as 3100).
8. Click OK to create the service. The service is displayed.

   

9. The next step is to bind a monitor to this service. Click the Service to Load Balancing Monitor Binding link. The Service Load Balancing Monitor Binding screen appears.

   

10. Click Add Binding. The Load Balancing Monitor Binding screen appears.

    

11. Click Select Monitor to display the list of defined monitors.

    

12. Select the health monitor that you created earlier (for example, CWE-HealthMonitor-9000). Click OK.
13. Click Bind. The health monitor is now bound to this service.

    

14. Click Close to close the Service Load Balancing Monitor Binding screen.
15. Click Done to return to the main NetScaler screen. The service that you just created is now listed.

    

Repeat these steps for each server-port pair. For example, if you have servers named CWE-2008 and CWE-2012 and TAP interfaces at ports 3100 and 3200, and you follow the naming convention described above, you will create services named CWE-2008-TAP3100, CWE-2008-TAP3200, CWE-2012-TAP3100, and CWE-2012-TAP3200. This ensures that you can monitor the interaction of each server with each TAP interface.

Next, for each server, you must configure a load balancing service with the web interface.

1. Click Add to create a new load balancing service.
2. In the Service Name field, type the service name. Here, since you are configuring a service for the web interface, the service name could be the name of the service plus "Web", such as CWE-2008-Web.
3. Select Existing Server.
4. From the Server dropdown list, select the server that you want to associate with this service (such as CWE-2008).
5. In the Protocol dropdown list, select HTTP.
6. In the Port field, type 80.
7. Click OK to create the service. The service is displayed.
8. The next step is to bind a monitor to this service. Click the Service to Load Balancing Monitor Binding link. The Service Load Balancing Monitor Binding screen appears.

   

9. Click Add Binding. The Load Balancing Monitor Binding screen appears.
10. Click Select Monitor to display the list of defined monitors.
11. Select the web interface monitor that you created earlier. Click OK.
12. Click Bind. The health monitor and web interface monitor are now bound to this service. The page indicates that the web page was accessed successfully.
13. Click Close to close the Service Load Balancing Monitor Binding screen.
14. Repeat these steps for each server.

The Services pane now displays the complete list of services that you have defined.
