txc(1M)                                                             txc(1M)

NAME
     txc - start a tracex measurement

SYNOPSIS
     /opt/SItracex/bin/txc rawtrace [-m entab] [-w] [-t sec] [-s size] [-p]
                           [-n prio] [-i sec]

DESCRIPTION
     Each tracex measurement is started using the txc command. Once called,
     the system starts to log its activities in the rawtrace file in binary
     form. See NOTES and tracex(5) for more detailed information on
     filename conventions.

OPTIONS
     -m entab
          The system activities to be logged are configured via an event
          table [see entab(4)].

          entab is the name of a file containing such a list. The
          /home/tracex/entab file is used if this option is not specified.

     -w   Outputs warnings due to buffer overflows.

     -t sec
          Ends measurement after sec seconds.

     -s size
          Ends measurement if the binary log file is size bytes in size.

          If both -t and -t are specified, the measurement is ended when
          the first cancellation criterion is met. Calling the snap(1M)
          command overrides both options.

     -p   The ps(1) command is executed at the start of the measurement. If
          this option is used, output is saved to a file. If rawtrace ends
          with .R, this file is called mname.Aps, otherwise it is called
          rawtraceAps.

     -n prio
          nice(1) prio is executed at the start of the measurement.

     -i sec
          The buffer used internally should be output after a maximum of
          sec seconds.

NOTES
     To be able to use the supplied makefile, the rawtrace binary log file
     must be called "mname.R", where mname is any character string used to
     identify the measurement [cf. tracex(5)].

     Detailed instructions and, in particular, a description of all meas-
     urement points (events) known to tracex, as well as the format of the
     files, can be found in the /home/tracex/doc/trxman00 file.
