Failure Notification
There are two different ways that the Apple Qmaster distributed processing system can
provide information about a problem.
Email Notification
When a processing service stops unexpectedly, Apple Qmaster sends a notification
email to the address that was entered in the Apple Qadministrator Cluster Preferences
dialog for that cluster. If no address was entered there, the email is sent to the address
in the Internet settings of the computer on which the cluster controller is enabled.
Log files for individual jobs or batches
If a particular job or batch fails, a log file is generated that describes this failure. You can
find the name and location of this log file through the Batch Monitor. Select the batch
or job in the History table of the Batch Monitor window, and click the Info icon. If any
log files were generated because of failures in the processing of the item, the names
and locations of those logs are shown.
