NAME
     entab - tracex event table

DESCRIPTION
     The entab file contains a table of all the events (measurement points
     in the Reliant UNIX kernel) known to tracex(5).

     A number and a symbolic name are assigned to an event in each line of
     the entab file.

     The events to be logged by txc(1M) can be influenced by changing the
     ON/OFF byte (0: disabled, 1: enabled). The entab.orig file contains a
     default event table. This table should not be changed, rather only
     copied to create variants.

     Structure of an entab line:

     ON/OFF byte   Event no.   Symbolic event name   Explanations

     The following events are logged by txc:

     Event no.   Event name    Description

         1       HEADER        Internal measurement point
         3       DONTCARE     Internal measurement point
         4       ENDMESS      End of measurement
         5       TRXVERS       tracex version

        11       SCHEDULE      A new process is further processed by
                               the CPU - End of scheduler
        12       STARTIDLE    An idle process is initiated as there

NOTES
     In multiprocessor systems, the microsecond timer used by tracex only
     functions approx. 3 minutes after the system is booted.

     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.
