This section lists the steps to create a threshold alert definition for a single device template or across multiple device templates from the VMware Pulse IoT Center UI.

  • Creating an alert definition across multiple device templates: You can create a single alert definition that works across multiple device templates. When you create alert definitions for multiple device templates, ensure that the metrics or properties for the alert definition symptom is common across all the device templates that you have selected.
  • Creating alert definitions for system properties: You can create an alert definition for triggering a threshold alert whenever a system property value meets the alert definition symptom.

Prerequisites

You must have the Create Alert Definition permission to perform this operation. For more information about roles and permissions, see Roles and Permissions.

    To set the threshold for triggering alerts, select the THRESHOLD tab and enter the following information:
    1. Under Symptom, select a metric or system property, its condition, and enter the metric value to trigger the alert.
