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
6 ABSTIME Date and time of measurement (start)
7 CONFIG System configuration
10 STARTSCHED Scheduler is started
11 SCHEDULE A new process is further processed by
the CPU - End of scheduler
12 STARTIDLE An idle process is initiated as there
is no process ready for computation.
13 ENDIDLE Scheduler is started
14 SCENTRY Start editing a system call
15 SCEXIT Finish editing a system call
16 NAMEXEC Name of the program loaded by exec
17 FORK A process is created. The measurement
point is output by both the parent pro-
cess and the child process.
18 EXIT Exit system call - End of a process
19 PAGEFLT Page error in the user's address space
20 PAGEIN Page is allocated (required page is in
the main memory)

32 FILENAME Name of the file that was opened during an
open or a create.
34 TXSIGNAL A process receives a signal
37 DROPPAGE Release page
38 SWAPIN Swap in process
39 SWAPOUT Swap out process
43 INTR External interrupt
46 TIMER Timer interrupt
47 STRPUSH STREAMS push

50 WAKEUPC Wakeup on channel
51 STRENTRY Entry to a STREAMS service procedure
52 STREXIT Exit from a STREAMS service procedure
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.
