The Scheduler is a tool that lets you schedule Functions to be run at a particular date and time.
Accessing the Scheduler
The Scheduler can be accessed from Settings - Scheduler.
If any scheduled functions have been set up already, you'll see them detailed here.
Each record contains the following:
The name of the scheduled task
The function that will be run
A schedule that determines when the function will be run
Scheduling a function
Click on Add New Record to schedule a task.
Enter a name for the scheduled task that gives users an idea of what it does.
Here you will determine how often the function will run - every hour, day, week, month, or year.
Use Custom Expression
This is an advanced option. In some cases, you may wish to run the function on a more complex schedule than the Schedule on controls allow.
Checking this option will replace those controls with a field that allows you to enter a custom expression.
A custom expression is a series of characters that is interpreted by the scheduler to form a more complex schedule.
Specifically, the scheduler accepts CRON expressions. There are tools online that can help you generate this.
Some example CRON expressions are shown below.
1st day of every third month at 9am
0 9 1 */3 *
Every Monday, Wednesday, and Friday at 1pm
0 13 * * 1,3,5
This is where you will select the function that will be run.
The scheduled task will no longer run after the entered date.
The task will only run if this box is checked. You can uncheck it to disable a task without having to delete it.
Enable Error Logging
Enabling this allows for logging of failed run attempts.
