System Trace Facility - User Guide
The OS/2 Trace facility is an important RAS mechanism within the OS/2 product.
It allows specific events within the operating system, in system extensions
and in applications to be recorded in a circular System Trace buffer. Software
developers can create tracepoints that are used to monitor the execution
of their software modules. A tracepoint is in essence a "window" that can
be used to "peek" into a software module whenever that module reaches the
state that corresponds to the tracepoint.
The OS/2 Trace facility includes three important utility programs:
TRACE
The OS/2 Trace control utility is
used to control (that is, enable and disable) the tracing of individual
events.
TRCUST
The
Dynamic Trace Customiser is
used to define both dynamic tracepoints for .DLL modules and trace formatting
files for use by TRACEFMT utility.
TRACEFMT
The Trace Formatter is used to format the
contents of the sytem trace buffer for viewing. It may also be used for
saving both formatted and unformatted trace data in a disk file and therefore
may be used with the Dump Formatter .TS
command to format a system trace buffer that has been captured in a
system dump.
