Trace control

When a PDT-enabled application starts, PDT reads its configuration from a file.

Environment variable

PDT supports an environment variable (PDT_CONFIG_FILE ) that allows you to specify the relative or full path to a configuration file.

ALF ships an example configuration file that lists all of the ALF groups and events, and allows the user to turn selected ones off as desired. This is shipped as 
/usr/share/pdt/config/pdt_alf_config_cell.xml
.
