Sorry,  when did we have cgi version monitor?

Aaron, The monitor system we plan to build up is only at job counting 
level. Querying the running pipeline database and then counting out how 
many analysis are there, how many jobs of each analysis is done or 
failed etc and a sort. And I do not think we are going to investigate 
at process level. Correct me, if I was wrong, other guys.
