all of the applications use logging 4 java (log4j for short).
Seach for the log4j.properties files on the system ... there should be one for each instance (CBM, and each data collector).
Ideally, you should be able to load the syslog module, and then configure log4j.properties to ship the information off to a syslog server.
There is a KB for vCloud Director, that can generally go over the process here ... but that being said, I haven't done it with Chargeback before.
