strerr(8) System Manager's Manual strerr(8)
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 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 message has also been saved in the process's trace log. Indi-
cates 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 subidentification number of the trace message source. The trace
The strerr daemon will run continuously until terminated by the user.
The error log file or files on which strerr operates.
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.
