Construct Expression

This section will guide you on how to construct an expression using the EXPRESSION EDITOR when adding an expression in the CMS. The goal here is to tell Senfi how to detect an event that you want to be notified of/should be responded to.

The Expression Editor is a graph-based Drag & Drop editor.

Expression Editor

Arrows coming in from the left of a node indicate its input and those going out from its right indicate its output.

Input & Output of a Node

Each Node falls into one of the following categories:

  • Asset Identifier
  • Input
  • Data Transformation
  • Logic
  • Result
  • Event

Data originates from Metric nodes, is transformed by Data Transformation and/or Logic nodes, and eventually consumed by Result & Event nodes.

See Node Type for more information about each Node Type.
