Use the Matching schedules tab of a context in the Matcher module of Lerian Console to run matching automatically. Each matching schedule sets when Matcher runs matching for the context.
Matching schedules set when automated matching runs. They do not pull data. To schedule when a source pulls data, use the ingestion schedules of the source.

​
Accessing schedules

1
In the Matcher sidebar, go to Configure → Contexts.
2
Click the name of a context to open its page.
3
Select the Matching schedules tab.
Scheduled matching runs only while the context is Active.

​
Schedule list

The tab lists the matching schedules of the context. Each row shows:
  • The cron expression
  • An Enabled or Disabled badge
  • The Last run and Next run times in UTC. An empty time shows —
  • An edit (pencil) button and a delete (trash) button

​
Creating a schedule

1
On the Matching schedules tab, click Add matching schedule. The Add matching schedule sheet opens.
2
Type the schedule in Cron expression (UTC), up to 100 characters. The placeholder is 0 2 * * *.As you type, a preview appears below the field. A common expression shows a phrase such as “Runs every day at 02:00 (UTC)”. An uncommon expression shows a generated phrase or “Custom schedule”. An expression with the wrong shape shows “Matching schedules take a 5-field cron expression, such as 0 2 * * *.”The preview does not block Save. Matcher checks the expression when you save.
3
Leave the Enabled switch on to create an active schedule. Turn it off to create a disabled schedule. A disabled schedule has no next run time, so it does not run.
4
Click Save.
Matcher reads a cron expression in UTC. It has five fields, separated by spaces: minute hour day-of-month month day-of-week.Special characters:
  • *: any value
  • ,: a list of values, such as 1,15,30
  • -: a range, such as 9-17
  • /: a step, such as */15 for every 15 units
Examples:
  • 0 6 * * *: every day at 06:00 UTC
  • */15 * * * *: every 15 minutes
  • 0 9 * * 1-5: at 09:00 UTC on weekdays
Matcher does not accept @every or other named macros. When you restrict both day-of-month and day-of-week, a match in either field starts the schedule. Use an interval of five minutes or more. Matcher refuses * * * * * and */2 * * * *.

​
Editing a schedule

Click the pencil button on a schedule row. The Edit matching schedule sheet opens with the current Cron expression (UTC) and Enabled values. Change the fields and click Save. For an enabled schedule, Matcher calculates Next run again from the current UTC time. When you disable a schedule, it loses its next run time.

​
Deleting a schedule

Click the trash button on a schedule row. A dialog names the schedule and asks you to confirm. Click Confirm.
You cannot undo a delete. The schedule does not run again.
