### Trace log
Trace log includes information about available servers and their states, client sessions, queries being executed, routing decisions and other routing related data. Trace log can be found from the same directory with other logs but it is physically stored elsewhere, to OSs shared memory to reduce the latency caused by logging. The location of physical file is : /dev/shm/<pid>/skygw_traceX.log where ‘X’ is the same sequence number as in the file name in the $MAXSCALE_HOME/log directory.

by default. If, however, trace and debug logs are enabled, only a soft link is created there. MaxScale process creates a directory under
/dev/shm/<pid>
/dev/shm/maxscale.<pid>
where it stores the physical trace and debug log files. Link and physical files share the same name. These logs consume the main memory of the host they run on so it is important to archive or remove them periodically to avoid unnecessary main-memory consumption.
