strerr (streams_error_logger_server) -writes error messages from STREAMS log driver to file
usage: [-h] | [-n name] | [-f format_file ]
DESCRIPTION
strerr 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 (not
implemented)
<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.
Messages that indicate the total failure of a STREAMS driver or module
have the F flag set. The priority level usually has no meaning in the
error log but has meaning if the message is also sent to a tracer
process.
Once initiated, strerr continues to execute until terminated by the user.
Commonly, strerr is 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 causes a degradation in STREAMS performance. If
a large burst of messages is 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.
