Overview
This node operation schedules a daily restart for a server using the WARest WhatsApp REST API. It allows users to specify a daily time for the restart or cancel a previously scheduled restart by setting the schedule to '0'. Additional optional fields include a reason for the restart, a delay in milliseconds before the restart occurs, and a timezone to correctly interpret the scheduled time. This operation is useful for automating server maintenance tasks to ensure the server restarts at a consistent time each day, which can help in applying updates or clearing temporary issues without manual intervention.
Use Case Examples
- Schedule a server to restart daily at 03:00 AM to apply updates automatically.
- Cancel a previously scheduled daily restart by setting the schedule to '0'.
- Schedule a daily restart at 02:30 AM with a 5-minute delay and specify the timezone as 'Asia/Jakarta'.
Properties
| Name | Meaning |
|---|---|
| Schedule (HH:MM or 0 to cancel) | The time of day to schedule the server restart in 24-hour format (HH:MM). Setting this to '0' cancels any scheduled restart. |
| Reason | Optional reason for scheduling the restart, useful for logging or notification purposes. |
| Delay (ms) | Optional delay in milliseconds before the restart is executed after the scheduled time. |
| Timezone | Optional IANA timezone string (e.g., Asia/Jakarta) to interpret the scheduled time correctly according to the server's timezone. |
Output
JSON
json- Response from the WARest API indicating the status of the scheduled restart operation
Dependencies
- Requires an API key credential for the WARest WhatsApp REST API and the base URL of the API server.
Troubleshooting
- Ensure the 'schedule' property is in the correct HH:MM format or set to '0' to cancel. Invalid formats may cause errors.
- If the server does not restart as scheduled, verify the timezone setting matches the server's timezone.
- Check API credentials and base URL configuration if the node fails to connect to the WARest API.
- Common error messages may include invalid schedule format, unauthorized access due to incorrect API key, or server communication errors. Verify all inputs and credentials are correct.
