STRERR(1M)           INTERACTIVE UNIX System           STRERR(1M)



          NAME
               strerr - STREAMS error logger daemon

          SYNOPSIS
               strerr

          DESCRIPTION
               The strerr routine receives error log messages from the
               STREAMS log driver [log(7)] and appends them to a log file.
               The error log files produced reside in the directory
               /usr/adm/streams, and are named error.mm-dd, where mm is the
               month and dd is the day of the messages contained 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

                    <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 driver or module should have the
               F flag set.  Those messages requiring the immediate atten-
               tion of the administrator will have the N flag set, which
               causes the error logger to send the message to the system
               administrator via mail(1).  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 will continue to execute until ter-
               minated by the user.  Commonly, strerr would be executed
               asynchronously.

          CAVEATS
               Only one strerr process at a time is permitted to open the

               STREAMS log driver.

               If a module or driver is generating a large number of error
               messages, running the error logger will cause a degradation
               in STREAMS performance.  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.
