Monitoring and Alerting
This workflow implements real-time monitoring and automatic alerting functions. It periodically queries abnormal sensor data from a Postgres database and automatically sends SMS alert notifications, ensuring that information is accurate, timely, and non-repetitive. It is suitable for scenarios such as industrial equipment and server performance, enabling automated monitoring of data thresholds, improving response speed, reducing the risk of human error, and helping enterprises enhance operational efficiency.
Workflow Name
Monitoring and Alerting
Key Features and Highlights
This workflow implements real-time monitoring and automated alerting based on scheduled tasks. It periodically queries abnormal sensor data from a Postgres database (records where values exceed thresholds and have not been notified), automatically triggers SMS alerts, and updates the database status to ensure alert information is accurate, timely, and not sent repeatedly.
Core Problems Addressed
- Automates monitoring of data thresholds to avoid manual oversight or missing anomalies.
- Provides timely notifications to relevant personnel, enhancing response speed.
- Prevents duplicate alerts by updating notification status in the database for alert deduplication.
Application Scenarios
- Monitoring industrial equipment or environmental sensor data.
- Automated alerting for server performance metrics or business indicators anomalies.
- Any scenario requiring real-time data monitoring with SMS notifications.
Main Process Steps
- Cron Scheduled Trigger: Periodically executes the workflow to check data.
- Postgres Query: Retrieves sensor data from the database where values exceed 70 and have not been notified.
- Twilio SMS Sending: Sends alert SMS messages to relevant personnel, including sensor ID and current value.
- Set Node Status Update: Marks alert records as notified.
- Postgres Update: Updates the notification status of corresponding records in the database to prevent duplicate alerts.
Systems or Services Involved
- Postgres: Stores and queries sensor data and notification status.
- Twilio: SMS sending service for alert notifications.
- Cron: Scheduled workflow triggering.
Target Users and Value
- Equipment maintenance personnel, monitoring engineers, and operations teams who require real-time monitoring of key metrics and rapid anomaly response.
- Enterprises aiming to automate operations and alert management to improve efficiency and reduce human error risks.
- Any business scenario needing automatic SMS notifications triggered by database data.
