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 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 : indi- cates a fatal error N : send mail to the system administra- tor (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 excep- tional conditions that require the attention of the system administra- tor. 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 sys- tem 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. FILES /var/adm/streams/error.mm-dd error log file.

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 situa- tion is indicated by gaps in the sequence numbering of the messages in the log files. SunOS 5.11 4 Oct 1994 strerr(1M)
