Unix operating systems have a system tool called top which shows current system cpu, memory, and process information.
It's updating output looks something like this:

Db2 offers a similar heads up tool for viewing aspects of the database performance and utilization.
It would be helpful to have a similar overview of the RPD system. For example the output could look something like:

Step Queue:
<Updating information: 10+ lines showing step tasks in queue order and how they are tuned (IE: what they are waiting on)>
Much like the DB2Top tool additional categories could be provided such as job, printer, input device, etc stats/status. For Jobs the output could track the number of jobs in processing, which states they are in. List which queued jobs and show the step/server they are queued for.
