You enable tracing using a configuration file that is defined to the Consolidated Tracing Facility by the MFTRACE_CONFIG environment variable. For example:
export MFTRACE_CONFIG=/home/mydir/ctf.cfg
The file specified by MFTRACE_CONFIG is processed during run-time system initialization and must be a text file. You specify the configuration information as name-value pair entries, with each entry on a separate line, and blank lines or lines beginning with ‘#’ treated as comment lines.
You also need to set the MFTRACE_LOGS environment variable to specify the default location for where the Consolidated Tracing Facility's log files are to be created. If MFTRACE_LOGS is not set, the current folder is used.
See Configuration File Entry List for a list of the types of entry you can specify in the configuration file.
