Using this data, you can easily monitor all database-to-database com-

database servers and create reports that filter on these source programs.
You can also create a report based on IP addresses: create a group of IP
addresses that includes all of your database servers and then look at a
report where the client IP and the server IP are in this group. This

will give you a monitor of database-to-database communications only.
Remember that using the IP group will show you access from your data-
base servers but not from a database server of which you may not be
aware. Therefore, the two reports are complementary and you should use

both
