If you archive log files by run, specify the number of text log files you want the Integration Service to create. The Integration Service creates the number of historical log files you specify, plus the most recent log file. If you specify five runs, the Integration Service creates the most recent workflow log, plus historical logs zero to four, for a total of six logs. You can specify up to 2,147,483,647 historical logs. If you specify zero logs, the Integration Service creates only the most recent workflow log file.
The Integration Service uses the following naming convention to create historical logs:
<session or workflow name>.n
where n=0 for the first historical log. The variable increments by one for each workflow or session run.
If you run a session on a grid, the worker service processes use the following naming convention for a session:
<session name>.n.w<DTM ID>
