 NAME
      strerr - receive error messages from the STREAMS log driver

 SYNOPSIS
      strerr [-a sys_admin_mail_name] [-d logdir]

 DESCRIPTION
      The strerr daemon receives error messages from the STREAMS log driver
      (strlog(7)) 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, strerr 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.  strerr then appends error messages to the log
      file as they are received from the STREAMS log driver.

      STREAMS error log messages have the following format:

	   seq time tick pri ind mod sub text

      Components are interpreted as follows:

	   seq	Error event sequence number.

	   time Time the message was sent expressed in hh:mm:ss.

	   tick Time the message was sent expressed in machine ticks since
		the last boot.

	   pri	Error priority level as defined by the STREAMS driver or
		module that originates the messages.

	   ind	Can be any combination of the following three message
		indicators:

		     T	  The message has also been saved in the trace log.

		     F	  The message signaled a fatal error.

		     N	  The message has also been mailed to the system
			  administrator.

	   mod	Module identification number of the error message source.

	   sub	Subidentification number of the error message source.

	   text Error message text.

      strerr runs continuously until terminated by the user.

    Options
      strerr recognizes the following options and command-line arguments:

      -a sys_admin_mail_name	    Specify the user's mail name for sending
				    mail messages.  Mail is sent to the
				    system administrator by default.

      -d logdir			    Specify the directory to contain the
				    error log file.  Default is
				    /var/adm/streams.

 WARNINGS
      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.	 strerr can degrade STREAMS performance by affecting the
      response, throughput, and other behaviors of the drivers and modules
      that invoke it.  strerr also fails to capture messages if drivers and
      modules generate messages at a higher rate than its optimum read rate.
      If there are missing sequence numbers among the messages in a log
      file, messages have been lost.
