  • System Monitor: The step of notifying JobScheduler through an acknowledgement in the System Monitor is an execution of a script. This is nothing else than a notification, like sending a mail for instance, but instead, another action is executed, which is the execution of the script that contacts JobScheduler and add an order to the JobChain ResetNotifications described above.
