Start task
Procedure

- The manager Qlik Sense Scheduler Service (QSS) on the central node communicates with each worker QSS to see which ones are available to perform the task.
-
The task is given to the currently available worker QSS with the least load according to the load balance rules.

In case of success, log entries are written in the following files throughout the procedure:
- <MachineName>_AuditActivity_Scheduler.txt
