PREVIOUS variable is not displayed when an alert is simulated

Table of contents

Updated December 8, 2017

Overview

In alert actions, it is possible to place the previous value of a variable into the trigger action. For instance, it is possible for the trigger action email to display the last time a node was booted prior to the instance that triggered the node reboot alert.

Environment

  • All versions of NPM and SAM

Detail

The PREVIOUS modifier of an alert variable is context sensitive. Because the data is not stored in the database, the prior value is kept for the duration of the trigger of the alert.

 

Hence, PREVIOUS variables in an alert will not resolve when the alert is simulated.
