Differentiate between sections within a single log file

I would do something very similar to the solution I proposed for the other format you had...

    if [message] =~ /^(\s*$|:::::)/ {
            drop {}
    } else if [message] =~ /^TIME/ {
            # parse it and stash it in a ruby class variable
    } else if [message] =~ "        .*      .*      " {
            csv {separator => "     " autodetect_column_names => true }
            # and append the metadata
    } else {
            drop {}
    }
