If you create a CONNECTION EVENT MONITOR , information about all applications will be captured at connect and disconnect time ...
If you parse it and load into a table , you can then get information at application level(including number of rows read) ... This may give a fair idea of what you want ...
Another option is to use db2 auditing, and capture data as and when connections happen ... This data can be loaded into a table using db2 facilites itself
