strerr(1M)

strerr -- STREAMS error logger daemon

Synopsis

strerr

Description

strerr receives error log messages from the STREAMS log driver log(7). The error log files produced 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

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 administrator via 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.

Notices

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 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.
