LS1.5 output to file, dots

[teebu (J)]

LS1.5 I want to output docs to a file, but file{} is outputting the whole event. i tried using: file {codec => dots} and file {codec => line {format => "."}} but its not doing it. It outputs the entire event json.

I guess im using an older output plugin, using message_format now.

file {
            message_format => "."
            path => "/path/to/logfile.log"
            gzip => true
            flush_interval => 10
        }
