These default actions are specific to Foglight Experience Viewer (FxV) integration. For more information about integrating with FxV, see Managing Request Integration with Foglight Experience Viewer .
You can create your own actions using a Groovy Script, as described in Creating actions.

Creating actions

You can use actions to collect additional information about your monitored environment. Actions are defined using Groovy scripts, and can apply to specific contexts, such as trace parameters, requests, or traces.
To create an action:
1
On the navigation panel, under Dashboards, click Application Servers > Nexus > Administration > Manage Actions.
2
Click Add.
3
In the Menu Item Text box, type the name you want to display in the action menu.
4
Optional — in the Description box, type a brief description for this action.
5
Select the Open in new window check box if you want the action to open in a new browser window.
 
* 
NOTE: This action varies depending on the web browser options you have set. You can have your options set to open a new window or a new tab in the current session.
6
In the Action Groovy Script box, type the Groovy script you want to apply.
This Groovy script is used to return an HTTP URL string that opens either a new web browser window or a Foglight for Application Servers WCF Iframe view.
For example, to open our company web page, type:
return "http://www.quest.com/";
7
In the Apply To selection, select one or more of the following contexts:
•
Request — Adds an action to the Request tab Action
•
Trace Parameter — Adds an action to the Single Trace HTTP Parameters table
•
Trace — Adds an action to the single trace Action column menu
8
Optional — in the Menu Item Display Groovy Script field, enter a Groovy script that evaluates to a boolean value. Users can use this to add extra logic to determine if an action should be displayed or not (for example, checking if FxV Integration is configured). If you leave this box blank, the menu item is always displayed.
The following example shows the action only if the request is not an HTTP request:
return !appserverAction_isHTTPRequest(@requestName);
9
Click OK. The dialog box closes and the Manage Actions dashboard refreshes.
