you need use multiline filter stream_identity set. documentation here isn't clear on it's used for, basic strategy this:

if (!"multiline" in [tags]) {   grok { // parse out identity field }   multiline {      stream_identity => "%{id}"     pattern => "." // match because we're gathering id field     => "previous"     periodic_flush => true     max_age => 5 // many seconds takes of lines     add_tags => ["multiline" ]   } } else {   // process multiline event that's been flushed }

i haven't tried since 1.5 came out, docs should work (in 1.4.2 , prior, flushing mechanism didn't work, lose events).
