Create an application through the Trigger API

An application is a user-defined container that you can associate with multiple devices and protocols for a unified view of built-in metrics. The ExtraHop Trigger API enables you to create applications with more complex filters than basic applications. For example, you can write a trigger to apply additional filters for collecting metrics, to create custom application metrics, or to collect metrics from non-L7 traffic.

1. Log in to the ExtraHop system through https://<extrahop-hostname-or-IP-address>.
2. Click the System Settings icon and then click Triggers.
3. Click Create.
4. Complete the information in the fields for Name, Author, and Description.
5. In the Events field, type HTTP and then select HTTP_RESPONSE.
6. Click the Editor tab.
7. In the Trigger Script textbox, type the following code:

   if (HTTP.processingTime > 500){
       Application("myAppID").commit();
   }

   Copy

   where "myAppID" is the permanent application ID. The value of "myAppID" is also applied as the display name, which can be modified later in the Web UI.

8. Click Save and Close.
