NAME

       strerr - STREAMS error logger daemon

SYNOPSIS

       strerr

DESCRIPTION

       strerr  receives error log messages from the STREAMS-based log driver (see log(7D)) and appends them to a log file. The resultant error log
       files  reside in the directory /var/adm/streams, and are named error.mm-dd, where mm is the month and dd is the day of  the  messages  con-
       tained in each log file.

       The format of an error log message is:

       <seq> <time> <ticks> <flags> <mid> <sid> <text>

       <seq>	  error sequence number

       <time>	  time of message in hh:mm:ss

       <ticks>	  time of message in machine ticks since boot priority level

       <flags>	  T  : the message was also sent to a tracing process F : indicates a fatal error N : send mail to the system administrator (hard-
		  coded as root)

       <mid>	  module  ID number of source

       <sid>	  sub-ID number of source

       <text>	  formatted text of the error message

       Messages that appear in the error log are intended to report exceptional conditions that require the attention of the system administrator.
       Those  messages	which  indicate the total failure of a STREAMS-based driver or module should have the F flag set. Those messages requiring
       the immediate attention of the administrator will have the N flag set, which causes the error logger to send  the  message  to  the  system
       administrator using mail. The priority level usually has no meaning in the error log but will have meaning if the message is also sent to a
       tracer process.

       Once initiated, strerr continues to execute until terminated by the user. It is commonly executed asynchronously.

NOTES

       There is no restriction to the number of strerr processes opening the  STREAMS-based log driver at a time.

       If a module or driver is generating a large number of error messages, running the error logger will cause a degradation in STREAMS  perfor-
       mance.  If  a  large  burst of messages are generated in a short time, the log driver may not be able to deliver some of the messages. This
       situation is indicated by gaps in the sequence numbering of the messages in the log files.

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.

   Options
       recognizes the following options and command-line arguments:

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

       Specify the directory to contain the error log file.
				     Default is

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.
