NAME
       strerr - 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.

FILES
       The error log file or files on which strerr operates
