Configuring Monitors in a Load Balancing Setup

Jul 05, 2017

To configure monitors on a Web site, you first decide whether to use a built-in monitor or create your own monitor. If you create a monitor, you can choose between creating a monitor based on a built-in monitor, or creating a custom monitor that uses a script that you write to monitor the service. For more information about creating custom monitors, see Custom Monitors. Once you have chosen or created a monitor, you then bind it to the appropriate service. The following conceptual diagram illustrates a basic load balancing setup with monitors.

Figure 1. How Monitors Operate

As shown above, each service has a monitor bound to it. The monitor probes the load balanced server via its service. As long as the load balanced server responds to the probes, the monitor marks it UP. If the load balanced server should fail to respond to the designated number of probes within the designated time period, the monitor marks it DOWN.
