Types of Delays

AAI can identify the following types of delays during jobstream execution related to the SLAs:

• Finish/Start delay

  Amount of time that lapses between the completion of a job, when all job conditions have been met, and the start of the next job. This delay indicates a system latency.

• Start/Running delay

  Amount of time that lapses between the activation of the job in the scheduler and the time of submission to the system. This delay indicates a possible latency in the scheduler or its hosting server. This can be caused by performance or processing capacity issues.

• Operational delay

  Delays caused by errors, restarts and human intervention. For example, a job fails to execute, an operator restarts it 30 minutes later, the operational delay is 30 minutes.

• Design delay

  Delays caused by flawed job design. For example, a predecessor job ends at 8 am and the job owner manually sets the critical path job to start at 9 am. This means that the jobstream will have a one hour design delay.

• Resource wait time

  Executions are held back while waiting for virtual resources to have enough capacity to execute the job.

• Unexpected delay

  Any sort of delay that does not fall in the previous categories.
