schedule_rack_scale_up

Description

The schedule_rack_scale_up parameter specifies the schedule for scaling up the rack using the Unix cron syntax format. Example: ‘0 0 * * 0’. The supported cron expression format consists of five fields separated by white spaces: [Minute] [Hour] [Day_of_Month] [Month_of_Year] [Day_of_Week]. More details on the CRON format can be found in Crontab and examples. The time is calculated in UTC.

Default Value

The default value for schedule_rack_scale_up is an empty string.

If the schedule_rack_scale_up parameter is set to an empty string, no scale-up schedule is applied by default. This parameter is optional and can be configured based on your specific needs.

Use Cases

• Performance Optimization: Schedule the rack to scale up during peak hours to ensure optimal performance.
• Resource Management: Ensure that resources are scaled up when needed to handle increased workloads.

Setting Parameters

To set the schedule_rack_scale_up parameter, use the following command:

$ convox rack params set schedule_rack_scale_up="0 0 * * 0" -r rackName
Setting parameters... OK

This command sets the rack scale up schedule to every Sunday at midnight UTC.

Additional Information

The schedule_rack_scale_up parameter is used in conjunction with the schedule_rack_scale_down parameter. Both parameters must be properly configured to ensure that the rack scales up and down according to the desired schedule.

Properly scheduling the scale up times can help you optimize performance and resource usage. Ensure that the cron expressions are set correctly and consider the time zone differences when setting the schedule. For more information on configuring cron schedules, refer to the Crontab documentation.
