NAME
strace - write STREAMS event trace messages to standard output
SYNOPSIS
mod sub pri
DESCRIPTION
gets STREAMS event trace messages from STREAMS drivers and modules via the STREAMS log driver and writes these messages to standard output.
By default, without arguments writes all STREAMS trace messages from all drivers and modules. with command-line arguments limits the trace
messages received.
The arguments, which must be specified in groups of three, are:
mod Specifies the STREAMS module identification number from the streamtab entry.
sub Specifies a subidentification number (often corresponding to a minor device).
pri Specifies a tracing priority level. gets messages of a level equal to or less than the value specified by pri. Only posi-
tive integer values are allowed.
The value can be used for any argument in the command line to indicate that there are no restrictions for that argument.
Multiple sets of the three arguments can be specified to obtain the messages from more than one driver or module.
Only one process can open the STREAMS log driver at a time.
When is invoked, the log driver compares the sets of command line arguments with actual trace messages, returning only messages that sat-
isfy the specified criteria.
STREAMS event trace messages have the following format:
seq time tick pri ind mod sub text
Components are interpreted as follows:
seq Trace event sequence number.
time Time the message was sent expressed in hh:mm:ss.
tick Time the message was sent expressed in machine ticks since the last boot.
pri Tracing priority level as defined by the STREAMS driver or module that originates the messages.
ind Can be any combination of the following three message indicators:
The message has also been saved in the error log.
The message signaled a fatal error.
The message has also been mailed to the system administrator.
mod Module identification number of the trace message source.
sub Subidentification number of the trace message source.
text Trace message text.
runs until terminated by the user.
EXAMPLES
Display all trace messages received from the driver or module identified by mod
Display trace messages of any tracing priority level from the driver or module identified by mod and its minor devices identified by the
sub or
Display the trace messages from the same driver or module and subs but limit the priority levels to 0 for subs 2 and 3; 1 for sub 4, driver
or module
WARNINGS
Running with several sets of arguments can impair STREAMS performance, particularly for those modules and drivers that are sending the mes-
sages.
Also be aware that may not be able to handle a large number of messages. If drivers and modules return messages to too quickly, some may
be lost.
