To enable CCI tracing, you must first enable CTF tracing, then edit the CTF configuration file, ctf.cfg, to trace the CCI component:
mftrace.comp.mf.cci = info
Once that has been set, you must then configure the degree of information traced using the CCITRACE environment variable or the [ccitrace_base] section of the cci.ini configuration file.
If you are also wanting to trace CCI information on a Fileshare server, you must activate tracing when the Fileshare server is started.
