The 'trace_logger' component can be used to easily gather, process and export different types of tracing data. Which subjects to select is configurable via session label policies and thread names. Which data to collect from the selected subjects can be configured for each subject individually, for groups of subjects, or for all subjects. The gathered data can be exported as log output. This is an example configuration of the 'trace_logger' component which shows the default value for each attribute except the policy.thread and policy.label: ! <config verbose="no" ! session_ram="10M" ! session_arg_buffer="4K" ! session_parent_levels="0" ! period_sec="5" ! activity="no" ! affinity="no" ! default_policy="null" ! default_buffer="4K"> ! ! <policy label="init -> timer" /> ! <policy label_suffix=" -> ram_fs" /> ! <policy label_prefix="init -> encryption -> " ! thread="worker" ! buffer="4K" ! policy="null" /> ! </config> For more details see os/src/app/trace_logger/README.
