I have done some work on reading in some of the process manager and lsf status files. These are event based so you would have to do some work to transform a series of events to a current state. The files I found interesting and still comprehensible are $LSFTOP/work/dna_cluster/logdir/lsb.events, $LSFTOP/work/dna_cluster/logdir/lsb.acct and $JSTOP/work/history/history.log. They are all easy prey for a datastep.
A more ready made approach would be to use the EOM DI Monitor. This is a web application that helps you monitor the SAS batch jobs in LSF. This is an open source development by EOM. Get in touch with Bart Heinsius for details. We use it to great satisfaction.
