Schedulers

The Qlik Sense Scheduler Service (QSS) manages the scheduled tasks (reload of Qlik Sense apps or user synchronization) and task chaining. Depending on the type of Qlik Sense deployment, the QSS runs as master, slave, or both on a node.

The Schedulers overview lists all the available schedulers. The following table presents the available fields and buttons. By default, only some of the fields are displayed. You can use the column selector (') to add fields.

Porada: You can adjust the column width by dragging the header border.
Node The name of the scheduler node.
Status

One of the following statuses is displayed:

  • Running

    The service is running as per normal.

  • Stopped

    The service has stopped.

  • Disabled

    The service has been disabled.

Porada: Click ] in the Status column for more detailed information on the status.

Tags The tags that are connected to the scheduler.
Type
  • Master: sends the task to a slave QSS within the site.
  • Slave: receives the task from the master QSS and executes the task.
  • Master and slave: when the master QSS also acts a slave QSS, on a single node site.
Max concurrent reloads The maximum number of reloads that the scheduler can perform at the same time.
Engine timeout (minutes) If the number for Max concurrent reloads is reached (a separate property), the request to start a new engine process is queued, waiting for the number of running reload processes to go below Max concurrent reloads. If this does not happen within the given time period, the request to start a new engine process is removed from the queue.
