Billable items
SchedulerX has two billable items: task scheduling CU and task hosting CU.
Task scheduling CU
The task scheduling CU for a single task run is equal to the number of workers used for that run. For example:
- For a standalone task, the task scheduling CU for a single run is 1.
- For a non-standalone task, the task scheduling CU for a single run is equal to the number of workers used for that run.
- For second-level tasks, scheduling is counted at most once per minute.
Note The total task scheduling CU is the sum of all scheduling CUs for the day.
Task hosting CU
The fee is calculated based on the total task hosting CU. The formula for a single SchedulerX application is as follows:
Task hosting CU for a single SchedulerX application = Number of enabled standalone tasks + (Number of enabled non-standalone tasks × Number of workers connected to the application)The total number of hosted tasks is the sum of tasks hosted across all your applications and is independent of how many times a scheduling task runs each day.
Important The following billing example is for reference only. The actual fee is based on the information on the console or purchase page of the Alibaba Cloud service that you purchase.
For example, you have two SchedulerX applications: A and B.
- Application A has 10 connected client workers, 8 enabled standalone tasks, and 2 enabled non-standalone tasks.
- Application B has 5 connected client workers, 2 enabled standalone tasks, and 3 enabled non-standalone tasks.
Your total daily task hosting CU is calculated as follows:
Total task hosting CU = (8 + 2 × 10) + (2 + 3 × 5) = 45Important The number of enabled tasks is based on the daily peak of concurrently enabled tasks. For example, if you create and delete 1,000 tasks within a day, but at any given time a maximum of 100 tasks are enabled, the billing is based on 100 tasks.
