Creating System Resource Monitoring Requests

		Creating System Resource Monitoring Requests
		Table 5-4 shows examples of how you might monitor system resources.

The job queue and ﬁle system resources have the INITIAL option set to give a baseline for comparison. The job queue threshold value decreases for the longer job queues because the longer something is in the queue, the more likely it is that a node needs to be load balanced.
