strerr - STREAMS error logger daemon




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,
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>

error sequence number

time of message in hh:mm:ss

time of message in machine ticks since boot priority level

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)

module ID number of source

sub-ID number of source

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.

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
