Dynamic variables/ message variables are additional information you can include in your alert message. They provide further clarity and enable you to gain more insight on the alert notification.
Alarm variables contain specific information related to the alarm which triggered the alert. By inserting alarm variables into the alert message, you can receive details such as the Alarm ID, Source, Category, Severity, Time, Event Type, Entity of the alarm and the Last polled value.
Custom Fields for Devices/ Interfaces append specific details regarding the source of the alarm (device/interface) that have been provided in the respective snapshot pages to the alert message. These fields can only be included, if they have already been configured in the device/interface description.
Some of the custom fields available are listed below for both devices and interfaces.
