Using syslog ============ Since mnoGoSearch version 2.1 indexer uses syslog to log its messages. Different verbose levels could be specified with -v option: 0 SILENT - supress all log. Bad idea, better use -l option. 1 ERROR - log only critical errors 2 WARNING - log warnings as well 3 INFO - add info messages to log. Default. 4 EXTRA - extra logging 5 DEBUG - for debug purposes You may use -l option to supress log to stdout/stderr when running indexer via crontab. Without -l option log is sent both to stdout/stderr and to log files. If you do not like such behavour, run configure with --disable-syslog flag and recompile indexer. Compiled without syslog support, indexer uses only stdout/stderr. Syslog uses different facilities to separate log messages. The indexer's default facility is LOCAL7. Facility could be changed during configure with --enable-syslog=LOG_FACILITY option. LOG_FACILITY should be one of the standard facilities, usually listed in /usr/include/sys/syslog.h header file. Facility helps to separate mnoGoSearch messages from others. You can modify /etc/syslog.conf to tell syslog how to treat mnoGoSearch messages. For example: # Log all messages from mnoGoSearch to separate file local7.* -/var/log/mnoGoSearch.log Other example: # Send all mnoGoSearch messages to host named central # Syslog on central should be configured to allow this local7.* @central By default all messages are logged to /var/log/messages as well. mnoGoSearch could populate this file with a number of messages. To avoid this, add local7.none or local7.!* (ignore any messages from local7 facility) to your 'catch-all' logfiles. For example: # # Some `catch-all' logfiles. # *.=info;*.=notice;*.=warn;\ auth,authpriv.none;\ cron,daemon.none;\ mail,news.none;\ local7.!* -/var/log/messages Please take a look at syslogd(8) and syslog.conf(5) man pages for more detailed information about syslog and it's configuration notes.
