NAMEstrerr — receive error messages from the STREAMS log driver DESCRIPTIONThe strerr daemon receives error messages from the STREAMS log driver ( strlog(7)) for addition to the STREAMS error log files (error. mm-dd) in the STREAMS error logger directory (/var/adm/streams by default). When first called, strerr creates the log file error.mm-dd. This is a daily log file, where mm indicates the month and dd indicates the day of the logged messages. strerr then appends error messages to the log file as they are received from the STREAMS log driver. STREAMS error log messages have the following format: seq time tick pri ind mod sub text Components are interpreted as follows:
strerr runs continuously until terminated by the user. WARNINGSOnly one strerr process can open the STREAMS log driver at a time. This restriction is intended to maximize performance. The STREAMS error logging mechanism works best when it is not overused. strerr can degrade STREAMS performance by affecting the response, throughput, and other behaviors of the drivers and modules that invoke it. strerr also fails to capture messages if drivers and modules generate messages at a higher rate than its optimum read rate. If there are missing sequence numbers among the messages in a log file, messages have been lost. |
