Foglight 7.1.0 - Web Component Tutorial

Invoking a Function from a Function

Support is available for invoking a function from the script text of a Script or Script with Map Function, or from a JavaTM Function. This is achieved by using this method of FunctionHelper:

Where:

For Script or Script with Map Functions, this method can be accessed via the functionHelper hidden parameter.

For Java Functions, the Java method for that function must have a parameter of type FunctionHelper, as previously described, so that the invoke method can be accessed via that parameter.

Example script that uses this functionality (where user.foglight.1 is a function that takes two integer inputs):

NOTE: Due to the way the Groovy scripting environment works, if you are calling a function that has no inputs, you can simply not provide the inputValues parameter at all (as opposed to providing null).functionHelper.invokeFunction("user:foglight.3");

Invoking a Query from a Function

Support is available for invoking a query from the script text of a Script or Script with Map Function or from a JavaTM Function. This is achieved by using the method FunctionHelper.invokeQuery().

How this method can be accessed and used is the same as the FunctionHelper.invokeFunction() method used for invoking a function from a function (as described in the previous section).

Time Range used for testing a function

When testing a Function through the Web Component Framework’s Function editor, be aware that the time range used by the Web Component Framework to evaluate a Function is a fixed (built-in) time range, which is from Jan 01, 2000 to Now (the time you started your test).

CAUTION: Testing is not supported using Internet Explorer 6

Bindings

This section describes the configurable properties for pages and views. Configurable properties determine which data items actually display in a View. Properties are set at design time. They are typically simple types, such as numerical and string values. The properties for each View are set in its Configuration tab. Examples are a parameterized title, formatting, and the source of its data values or metrics.

Each configurable property has a specified data type. There are simple types and binding types. Simple types are types such as strings or numbers. For example, the font size property is a number. Simple types are typically for formatting or labeling properties.

The binding types are used to retrieve the dynamic data in a view. The values of these properties are extracted from data objects at run time. For example, all of the monitored hosts can be extracted from the Host data object.
