PROGRAM:
NAME
stap-merge - systemtap per-cpu binary merger
SYNOPSIS
stap-merge [ OPTIONS ] [ INPUT FILENAMES ]
DESCRIPTION
The stap-merge executable applies when the -b option has been used while running a stap
script. The -b option will generate files per-cpu, based on the timestamp field. Then
stap-merge will merge and sort through the per-cpu files based on the timestamp field.
OPTIONS
The systemtap merge executable supports the following options.
-v Verbose mode, displays three extra fields per set of collected data.
[cpunumber,sequencenumberofdata,thelengthofthedataset]
-o OUTPUT_FILENAME
Specify the name of the file you would like the output to be redirected into. If
this option is not specified than the output will be pushed to standard out.
EXAMPLES
$ stap -v -b -e 'probe syscall.open { printf("%s(%d) open\n",
execname(), pid()) }'
This should result in several stpd_cpu files (each labled with a number representing which
cpu the file was produced from).
$ stap-merge -v stpd_cpu0 stpd_cpu1
Running the stap-merge program in the same directory as the stap script earlier in the
example, will produce an ordered sequence of packets with the three part label for each
set of data. This result will be pushed through the standard output. An output file
could have been specified using the "-o" option.
