[syslog-ng] Hosts Logging Into Multiple Destinations (files) Bad Filter???

Fri Jan 18 17:37:50 CET 2008

Ah!  So, if I want to log to my database, as well as just *one* other flat file location, then I should place my destination for DB first, followed by the others for flat files, each with it's own 'final' statement?

destination D_db_mysql {pipe("/var/log/mysql.pipe" template("INSERT INTO logs
(host, facility, priority, level, tag, datetime, program, msg)
VALUES ( '$HOST', '$FACILITY', '$PRIORITY', '$LEVEL', '$TAG', '$YEAR-$MONTH-$DAY $HOUR:$MIN:$SEC',
'$PROGRAM', '$MSG' );\n") template-escape(yes));

destination D_accesspoints { file("/var/log/ABCcorp/accesspoints/$FULLHOST.log" perm(0644)); final };

destination D_udp { file("/var/log/ABCcorp/$FULLHOST.log" perm(0644)); final };

Is this the correct location for final?  

Thanks again,

.vp

> Incoming messages are sent along *all* log paths that match. Every message that arrives from S_udp will be sent to D_udp and also to D_db_mysql. Some of those messages will also be sent along some of the more specific paths. If you don't want this to happen you can use the "final" keyword on the more specific paths.
