NAME

       strerr - receive error messages from the STREAMS log driver

SYNOPSIS

       sys_admin_mail_name] logdir]

DESCRIPTION

       receives  error	messages  from	the STREAMS log driver (strlog(7)) for addition to the STREAMS error log files mm-dd) in the STREAMS error
       logger directory by default).  When first called, creates the log file This is a daily log file, where mm indicates the month and dd  indi-
       cates the day of the logged messages.  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:

			The message has also been saved in the trace log.

			The message signaled a fatal error.

			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.

       runs continuously until terminated by the user.

				     Mail is sent to the system administrator by default.

WARNINGS

       Only one 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.	can degrade STREAMS performance by affecting the response,
       throughput, and other behaviors of the drivers and modules that invoke it.  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.
