Determining maximum size of a trace log

Each entry that is made to a trace log file created that uses a destination of FILE, TEXTFILE, or UTF8FILE is an average of 200 bytes in size. The maximum size of a log file, in bytes, can be estimated as follows:

200 × (Number of log files) × (Number of entries per log file)

For example, given a specification of:

*:*.9:TEXTFILE.10.10000:C:/PROGRA~1/Tivoli/POLICY~1/log/trace__%ld.log

The maximum size would be approximately (200 × 10 × 10000) or 20,000,000 bytes. Trace entries that are written in XML log format are an average of 500 bytes in size, thus for a specification of:

*:*.9:XMLFILE.10.10000:/var/dbug20031028A/trace__%ld.xml

The maximum size would be approximately (500 × 10 × 10000) or 50,000,000 bytes.
