syslog-ng documentation wrong

http://www.observium.org/wiki/Syslog-ng_Syslog_Server:

program("/opt/observium/syslog.php" template ("$HOST||$FACILITY||$PRIORITY||$LEVEL||$TAG||$YEAR-$MONTH-$DAY $HOUR:$MIN:$SEC||$MSG||$PROGRAM\n") template-escape(yes));

The macro "$PRIORITY" is actually an alias for $LEVEL and therefore it will add the severity word to the database field instead of the expected number.

It needs to be changed to: $LEVEL_NUM

LEVEL_NUM:
Description: The priority (also called severity) of the message, represented as a numeric value, for example, 3. For the textual representation of this value, use the $LEVEL macro. See Section PRIORITY or LEVEL for details.

program("/opt/observium/syslog.php" template ("$HOST||$FACILITY||$LEVEL_NUM||$LEVEL||$TAG||$YEAR-$MONTH-$DAY $HOUR:$MIN:$SEC||$MSG||$PROGRAM\n") template-escape(yes));
