We have about a thousand customers with our application installed out of which 500 have an oracle database.
Monitoring the database is only one of the requirements.
Installing Oracle Enterprise Manager will give me all the info I need for my databases but no information for the other important metrics (we got some synchronization going on through database link) and a number of process which should be up and running outside of the db.
So my question boils down to this: Is there an oracle rdbms API I could use to integrate the oracle metrics we need in our monitoring tool?
