Working with Application Instances

An application instance is a running copy of an application profile that monitors the defined collection of components, distinct applications, and thresholds necessary to define the health and performance of a given type of application. An application instance can extend the application profile by adding components, component groups, or discrete applications. The application profile is not changed when an application instance is extended.

Important: In order to perform these procedures, you must have the Configure APM Application Instances user right enabled.

To create an instance for monitoring an application on a specific device:

Select an application type displayed, then select New Instance from the Options menu for the applicable profile.
OR

Select an application profile displayed, then click Add Application Instance. The Configure New Application Instance page appears.
Configure the following:
- Enter a Name and Description for the application instance.
- Select any Attributes to apply to the instance if desired.
- Click the Browse button (...) and use the dialog displaying the device tree that appears to select a test device for the instance.
- Specify the maximum duration in seconds before the test will time out in the TEST Timeout field.
- Select a configured action policy using the Action Policy list to apply to the instance, if desired.
- Enable the In Maintenance option to place the instance in maintenance mode. While in maintenance mode, the application instance will not be monitored.

In addition to these basic instance configuration elements, you can also use the controls on the Components grid on this page to:

Add components to or remove components from the instance.
Create critical component groups.
Create copies of components within the instance.
Test any or all components within the instance.
Modify the polling frequency for one or more components within the instance
