When the trace facility is active, information about these events is recorded in a system trace log file. The trace facility includes commands for activating and controlling traces and generating trace reports. Applications and kernel extensions can use several subroutines to record additional events.

With this command, you can control the size and manage the trace log file as well as the internal trace buffers that collect trace event data.
Extracts trace information from a system dump.
If the system halts while the trace facilities are active, the contents of the internal trace buffers are captured. This command extracts the trace event data from the dump and writes it to the trace log file. A kernel name list is composed of a symbol table and a loader symbol table of an object file. The trcrpt command ues the kernel name list file to inerpret addresses when formatting a report from a trace log file. The trcrpt command will use the trace formatting templates to determine how to interpret the data recorded for each event.
