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 in a logical way and the data generated in the node can be used as inputs for its next node. See Operating on Qapp Nodes for mode details about extending nodes in a Canvas.

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.

3.Define Analysis and Alert.
