strerr(ADM)                     19 June 1992                     strerr(ADM)


 Name

    strerr - STREAMS error logger daemon

 Syntax

    strerr

 Description

    The strerr daemon receives error log messages from the STREAMS log driver
    (see log(M)) and appends them to a log file.  The error log files pro-
    duced 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 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

    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
    attention of the administrator will have the N flag set, which causes the
    error logger to send the message to the system administrator via mail(C).
    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 terminated by the
    user.  Commonly, strerr would be executed asynchronously.

 Notes

    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.
