Troubleshooting Jobs

You can view potential job problems from the Job Alerts page. This page is available from the Alerts table on the Overview page. The Pending Time and Deadline job alert parameters can be alarmed so that if the values pass a specified threshold, an alert will be generated and appear on the Overview Alerts table.

Figure 8–4 Job Alerts List Page

The Job Alerts page shows the following information:

• Job ID – The unique identifier for the job. Clicking on the Job ID brings you to the Job Details page.

• Task – The currently executing task. Some jobs consist of a single task (in which case, the task ID is always 1.) However, parallel jobs and array jobs each consist of more than one task. The tasks are usually numbered in ascending order starting with 1. Depending upon how the job was submitted, sometimes the numbers might skip as in 1,3,5. On running jobs, each task runs distinctly and so has its own configuration information, environment, and trace. For details about the task, click the task number to display the Task Details page.

• Job Name – The name assigned to the job.

• Pending time – How long the job has been waiting to be assigned to a queue.

• Deadline – The time specified by which a job must start or generate an alarm.

See the qstat man page for more information about alarms and thresh holds.
