NAME
strerr - Receives error messages from the STREAMS log driver
SYNOPSIS
/usr/sbin/strerr [-a sys_admin_mail_name] [-d logdir]
PARAMETERS
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.
DESCRIPTION
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 where: 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
boot. Can be any of the following indicators: Indicates that the mes-
sage has also been saved in the process's trace log. Indicates that
the message signaled a fatal error. 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 subiden-
tification number of the trace message source. The trace message text.
The strerr daemon will run continuously until terminated by the user.
FILES
The error log file or files on which strerr operates.
NOTES
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 re-
sponse, 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 indi-
cate that messages have been lost.
