NAME
strerr - STREAMS error logger daemon
SYNOPSIS
strerrDESCRIPTION
strerr receives error log messages from the STREAMS-based log driver
(see
log(4D)) 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-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.

attributes(7)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
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.
