The first time the -traceon
keyword is used, it initializes tracing, creating a file
tracename
.TRC000 which receives the binary tracing data. If a trace file of the name
tracename .TRC000 already exists the binary trace data is appended to the end of the
file.
To start a fresh trace file, first turn off tracing then turn it back on again using a different
tracename . See Data File Management below for more information on file naming.
If
-file is omitted, binary trace output goes to standard output. If standard output is a
terminal device, an error message is issued and no tracing is generated.

(Abbr.: -fm)
Requires the -card option.
HP-UX servers (Series 800) and X.25 only.
Set the X.25/800 interface card logging mask to level 0, 1, or 2. The default level is 0.
The X.25/800 interface logs a standard set of messages. A level of 1 specifies cautionary
messages as well as the default messages. A level of 2 specifies information messages in
addition to the cautionary and default messages. This option is recognized only by the
ns_ls_x25 subsystem.
-log class ... (Abbr.: -l)
Requires the -entity option.
Control the class of log messages that are enabled for the subsystems specified by the
-entity option.
class specifies the logging class. Available classes are:
Full Abbr. Mask
informative i 1
warning w 2
error e 4
disaster d 8
informative Describes routine operations and current system values.
warning Indicates abnormal events possibly caused by subsystem prob-
lems.
error Signals an event or condition which was not affecting the
overall subsystem or network operation, but may have caused
an application program to fail.
disaster Signals an event or condition which did affect the overall sub-
system or network operation, caused several programs to fail
or the entire node to shut down.
Classes can be specified as keywords or as a single numeric mask depicting which classes
to log. The mask is formed by adding the individual masks of the log classes. If you
choose to indicate several classes at once, be sure to separate each log class with a space.
disaster logging is always on. The default logging classes for each subsystem is
configured into the configuration file, /etc/nettlgen.conf. When the
tracing/logging facility is started, the information in the configuration file is read and
subsystems are enabled for logging with the specified classes. To change the log class,
use the "nettl -log class -entity subsystem" command with a new log class
value. If desired, the command can be run for different log classes and different entities.
-m bytes Specify the number of bytes (bytes) of each trace record to trace. This option allows you
to specify the number of bytes to be captured in the trace packet. You may prefer not to
capture an entire PDU trace, such as when you are only interested in the header.
The maximum value for bytes is 2000. By default, the entire packet is traced. A value of
0 will also cause the entire packet to be traced. This option currently applies only to ker-
nel subsystems.
-mem init_mem [max_mem]
