Performance Threshold: Compute Cluster - Number of queued jobs

Performance_Threshold__Compute_Cluster___Number_of_queued_jobs_1_Rule (Rule)

Knowledge Base article:

Management Pack

Summary
This rule generates an alert when the number of queued jobs in the cluster surpasses the threshold value. These are jobs have not yet been sent to cluster nodes for processing. The default threshold value is 15. You can configure the threshold value for this rule on the Threshold tab of the rule properties.

Causes
Queued jobs are waiting for cluster resources in order to run. The most probable cause for an excessive number of queued jobs is that insufficient resources (such as number of nodes or processors) are available to run these jobs. Numerous queued jobs can also result if the CCS job scheduler is down.

Resolutions
To resolve this problem, verify the health of the cluster by doing the following: Check the Compute Cluster 2003 view in the State view and then click on the Head Node column to make sure the Scheduler service on the head node is running. Check the Alert view to make sure there is no error raised regarding unreachable nodes. Make sure you use the best scheduling practices recommended in http://technet2.microsoft.com/WindowsServer/en/library/899d300f-80cd-4b49-83ef-05e2b418a6371033.mspx?mfr=true
