strerr(1M)
NAME
strerr - STREAMS error logger daemon
SYNOPSIS
strerr
DESCRIPTION
strerr receives error log messages from the STREAMS 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 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 (hardcoded 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 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 adminis-
trator 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 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 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.
