Item prototype

The item prototype object has the following properties.

Property Type Description

Multiple intervals are separated by a semicolon.
User macros and LLD macros may be used. A single macro has to fill the whole field. Multiple macros in a field or macros mixed with text are not supported.
Flexible intervals may be written as two macros separated by a forward slash (e.g. {$FLEX_INTERVAL}/{$FLEX_PERIOD}).
