Introduction to Triggers
Triggers give you the ability to set an action that will occur on a specified condition for a real-time data stream.
For example, if the Refrigerator(temperature_F) > 42, send a text message alert. Triggers are processed server-side, in real-time for streaming data. Current supported actions for triggers are email and SMS alerts. Current supported conditional operators are >, >=, <, <=, =, matches value, increases by, decreases by, enters location, and exits location.
Recipient phone numbers and email addresses must be verified before alerts can be sent to those destinations. The verification process will be initiated the first time a new email address/phone number is used.
Use Cases
- Send a SMS alert if temperature gets too warm inside a refrigerator.
- Send an email if a process exits.
- Send a SMS alert if the number of active GPUs decreases.
- Send a SMS alert when my GPS tracker enters within 1 km of a location (geofence example).
Custom Message Templates
Email and SMS messages can be customized with images, links, instructions, emojis, and more. Detailed information on setting custom message templates can be found here.
