Use this page to specify the method to be used to determine the availability of the Web application. Availability can be based on either of the following:
Service Test Based Availability - If you select this option, availability is based on the availability of the test or successful execution of the service test. You can define several tests and designate one or more tests as "Key Tests". All tests can be executed by any of the "Key Beacons" in different geographical locations. A Web application is considered available if the key tests can be executed successfully by one or more key beacons. Additionally beacons also collect response time metrics as a result of executing the service test. These additional metrics are listed in Collected Metrics section at the bottom of the page.
System Based Availability - Availability can also be based on the underlying system that hosts the Web application. A system consists of components such as hosts, databases and other targets. Select the components that are critical to running your Web application and designate one or more components as 'Key Components'. These key components are used to monitor the Web application. The Web application is considered available as long as the key components are up and running.
If the availability is based on service test, you can select the following options:
All key service tests are successful. This option is recommended.
At least one key service test is successful.
If availability is based on the availability of underlying system components, make sure you have created that system first in Enterprise Manager.
If availability is to be based on a system, you need to specify the key components that are critical to running the service. You also need to specify if all key components need to be up in order for the Web application to be considered available, or if it is sufficient that at least one key component is up in order for the Web application to be considered available.
