you can get all job count order on some particular date ( upto 90 days) using reporting facility -> workload report.
however for particular application job count is not available using this .
further now you can put a small script on your control-m server to count number of jobs everyday on particular application , and get sysout in email to your email id
SQL << EOF
select count(*) from CMR_AJF where APPLIC = 'XXAplication name' ;
run this script on control-m server with control-m server user , 4-5 min before NDP.
Hope this will help you
