Description
This workflow automatically queries a Postgres database to find outlier readings for which SMS notifications have not been sent.
This is Workflow 2 in the blog tutorial Database activity monitoring and alerting.
Prerequisites
A Postgres database set up and credentials
A Twilio account and credentials
Nodes
Cron node triggers the workflow every minute, so the database is queried at regular intervals.
Postgres nodes extract values from, and update values in the database.
Twilio node sends an alert SMS about the outlier reading to a specified phone number.
Set node sets the notification value to true.
