strerr - Receives error messages from the STREAMS log driver
/usr/sbin/strerr [-a sys_admin_mail_name] [-d logdir]
Specifies the mail name of the user to receive the message via mail.
This is the system administrator by default.
Specifies the directory to contain the error log file. This is
/var/adm/streams by default.
The strerr daemon receives error messages from the STREAMS log driver
(strlog) for addition to the STREAMS error log files (error.mm.dd) in the
STREAMS error logger directory (/var/adm/streams by default). When first
called, the strerr daemon creates the log file error.mm.dd. This is a
daily log file, where mm indicates the month and dd indicates the day of
the logged messages. The strerr daemon then appends each error message that
it subsequently receives from the STREAMS log driver to the log file.
STREAMS error log messages have the following format:
seq_num std_time ticks_time flags mod_ID sub_ID msg_text
The error sequence number.
The time the message was sent, in the format hh:mm:ss.
The time the message was sent, measured in machine ticks since the last
Can be any of the following indicators:
T Indicates that the message has also been saved in the process's
F Indicates that the message signaled a fatal error.
N Indicates that the message is to be sent to the system
administrator or specified user via mail.
The module identification number of the trace message source.
The subidentification number of the trace message source.
The trace message text.
The strerr daemon will run continuously until terminated by the user.
Only one strerr process can open the STREAMS log driver at a time. This
restriction is intended to maximize performance.
The STREAMS error logging mechanism works best when it is not overused.
The strerr daemon can degrade STREAMS performance by affecting the
response, throughput, and other behaviors of the drivers and modules that
invoke it. The daemon will also fail to capture messages if drivers and
modules generate messages at a higher rate than its optimum read rate.
Missing sequence numbers among the messages in a log file indicate that
messages have been lost.
