Changes in SNAplus2 Functions in R6.0 and later releases
Trace File Format
Chapter 460
Trace File Format
Trace information for kernel components is stored now in binary files.
These files can be processed using new command-line utilities to select
specific information and to format it as readable ASCII text. The text file
format generated is different from the SNAplus format. The
command-line utilities to process trace information are as follows:
snapfilter Filter trace files to include only the required
information.
snaptrcfmt Format trace file information into ASCII text, readable
using a standard text editor.
For more information about these utilities and the trace file format, refer
to the chapter on tracing in the HP-UX SNAplus2 Administration Guide.
Tracing on user-space applications is still stored in ASCII text files, as in
SNAplus. The only difference in the trace format is that message data is
interpreted both as EBCDIC and as ASCII, in two separate columns,
rather than being interpreted character by character as either ASCII or
EBCDIC.
