Oracle SQL for Session Monitoring

Experts -

I would like to get the alert triggered if session > 40 connections from a single app server.

This is something will work

(select count(*) cnt, machine from gV$SESSION where lower(machine) like '%Application%' group by machine)

How can I set this up?

Thanks,
sve

you could poll periodically with dbms_scheduler

if your count > 40 then use utl_smtp to send notification

or, use a logon trigger, so that every user gets checked, if they are coming from the app server then do a count and send email if count > 40.  You could block them too if you wanted.
