strerr(ADM)
strerr --
STREAMS error logger daemon
Syntax
strerr
Description
The strerr daemon receives error log messages
from the STREAMS log driver (see
log(M))
and appends them to a log file.
The error log files produced
reside in the directory /usr/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
where:
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(C).
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 will continue to execute until
terminated by the user.
Commonly, strerr would be executed asynchronously.
Limitations
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.
