[syslog-ng] help with SDATA

Based on the following structured syslog, I am trying to extract the reason from the SDATA portion of the log. 2012-02-05T16:24:45.368 RT_FLOW - RT_FLOW_SESSION_CLOSE [junos@2636.1.1.1.2.36 reason=\”unset\” ] Problem I think I am running into is the value-pair that I am trying to extract includes the dots so the parser thinks its nested information destination d_mongodb { mongodb( value-pairs( scope("everything") key(".SDATA.junos@2636.1.1.1.2.36.reason") ) ); }; Thoughts? Any help is greatly appreciated. Chris
