Template notes

This flow monitors a file for changes of its content. If changed, an alert is sent out and you receive it as push, SMS or voice call on [SIGNL4](https://www.signl4.com).

User cases: - Log-file monitoring - Monitoring of production data - Integration with third-party systems via file interface - Etc.

Sample file "alert-data.json":

{ "Body": "Alert in building A2.", "Done": false, "eventId": "25180887437222013724ee5617b-2731-4d38-8e16-e4148b8fb8a0" }

Body: The alert text to be sent. Done: If false this is a new alert. If true this indicated the alert has been closed. eventId: Last SIGNL4 event ID written by SIGNL4.

This flow can be easily adapted for database monitoring as well.
