MS SQL Trace event collector for SSIM 4.8

I am trying to understand how this event collector works.

I know I am using a SQL 2005 server and I must put in the jdbc driver, host name, port, database name, dba user name, and dba user password.

What throws me is that it also wants a file name and want to either read from the beginning or from the end.

These trace files I want to roll over since there is a size limit on them.

Will this event collector work in this way and do I just need to point to the first trace file in this folder?

Thanks in advance,

Michael
