strerr receives error log messages from the STREAMS 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 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
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.
