Variables in OpManager are used to insert real-time data into workflows, notification messages, and webhook payloads. They act as dynamic fields that automatically pull in values like device name, IP address, alarm severity, and timestamp when an event is triggered.
For example, in a notification profile, you can use variables to include the device name and alarm details in an email or SMS. In workflows, variables let you perform actions based on the specific device or alarm that triggered the workflow. When sending data to external systems via webhook, variables ensure the payload contains accurate, relevant details from OpManager events.
The following variables help you automate responses, get useful alerts, and integrate with other tools without manually specifying any values.
