Axeda Groovy Scripto: Get Asset Alarms

[#1]

This script will return, in XML format, details of all alarms for a particular asset, identified by serial number.

It is designed to be called as a web service, in which case the username parameter will be supplied by the platform from the user authentication information passed in the web service call, and the id parameter will be supplied as an argument to the call. You should define this script as a Custom Object of type Action.

You can test this script in the Groovy development environment on the platform by explicitly supplying the username and id parameters (i.e., your email address and "asset1").
