strerr(8)strerr(8)NAMEstrerr - Receives error messages from the STREAMS log driver
SYNOPSIS
/usr/sbin/strerr [-a sys_admin_mail_name] [-d logdir]
OPTIONS
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
The error sequence number. The time the message was sent, in the for‐
mat 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 message has also been saved in the process's trace log. Indi‐
cates that the message signaled a fatal error. Indicates that the mes‐
sage 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.
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
response, throughput, and other behaviors of the drivers and modules
that invoke it. The daemon will also fail to capture messages if driv‐
ers 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.
