Description
Workflow Purpose
This workflow periodically checks a service’s availability and sends an SMS notification if the service is down.
High-Level Steps
Schedule Trigger: The workflow is triggered at a specified interval, such as every minute. HTTP Request: An HTTP request is sent to the URL of the service being monitored. If: The HTTP status code of the response is checked. If the status code is 200 (OK), the workflow ends. If the status code is not 200, indicating a potential issue, an SMS notification is sent using Twilio.
Setup
Setting up this workflow is relatively straightforward and should only take a few minutes:
- Create a new n8n workflow.
- Add the nodes: Schedule Trigger, HTTP Request, If, and Twilio.
- Configure the nodes:
- Schedule Trigger: Specify the desired interval.
- HTTP Request: Enter the URL of the service to be monitored.
- If: Set the condition to check for a status code other than 200.
- Twilio: Enter the Twilio account credentials and the phone numbers for sending and receiving the SMS notification.
- Connect the nodes: Connect the nodes as shown in the workflow diagram.
- Activate the workflow: Save the workflow and activate it.
Additional Notes
- The workflow can be customized by changing the interval, the URL, the Twilio credentials, and the SMS message.
- This workflow is a simple example, and more complex workflows can be created to meet specific needs.
