A Canvas contains an independent workflow from retrieving device data to analyzing data to outputting results. Canvas consists of multiple nodes and their relations as well as functions are illustrated as follows:

Each node in one Canvas is connected to its upstream or downstream node logically, and the data generated in a node can be used as inputs for its next node.

Tip: You can define filter criteria on the Execution Flow tab to specify the devices that the Qapp applies to. If left empty, it means that the Qapp applies to all device types. See Filter Criteria for details.

Complete the following three steps:

1.Define Device Queue and Device (this).

2.Define Command and Parser.
