strerr(1M) System Administration Commands strerr(1M)
NAME
strerr - STREAMS error logger daemon
SYNOPSIS
strerr
DESCRIPTION
strerr receives error log messages from the STREAMS-based 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 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 (hard-
coded 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.

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 perfor-
mance. 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.
