The configuration mechanism of PRIS supports basic variable substitution.
Therefore it is possible to add properties to the global.properties file and reference the property values in any requisition.properties file.
Properties defined in the global.properties can be overwritten in a requisition.properties file.
It is also possible to use properties defined in a requisition.properties in a different part of the same requisition.properties again.
An implicit property requisition is also available in requisition.properties by default.
The following examples demonstrate the use of properties as variables in a PRIS configuration.
With the following configuration Nodes from the OpenNMS Demo system will be fetched.
To get the information a authentication is required and provided as a global configuration parameter.
The requisition for this example is named opennmsdemo.
