The following query finds total run-time (in minutes) for a concurrent program. You can make a small modification to this query, you can track which concurrent programs take (very) long time to complete, and may need performance tuning.
SELECT /*+ rule */

tl.user_concurrent_program_name "Program Name",
rq.actual_start_date "Start Date",

ROUND((rq.actual_completion_date -
rq.actual_start_date) * 1440, 2) "Runtime (in Minutes)"
