    Command:

    stap-merge

    
    
    
    

    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  out-
                  put 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.
