Configure this page to determine which tools can monitor whether the application server(s) are up. These can include the Admin Console, Device Services, Device Management, and Self-Service Portal. By default any load balancer or monitoring tool can perform this monitoring. For security purposes you can control this monitoring by IP address.
For example, you can set up a load balancer to detect if a given application server is up. The Admin Monitoring settings page lets you whitelist certain IP addresses that can access this page. By default, any IP address is allowed if no IP addresses are defined.
