The events are delimited by a line of underscores, so you could use a multiline codec to combine all the lines for a single event.

```
file {
    path => "/home/user/foo.txt"
    sincedb_path => "/dev/null"
    start_position => beginning
    codec => multiline {
        pattern => " _______"
        negate => true
        what => previous
        auto_flush_interval => 2
        multiline_tag => ""
    }
}

```

Then use grok

```
        grok {
        break_on_match => false
        match => {
            "message" => [
                "Timestamp%{SPACE}:%{SPACE}(?<Timestamp>[^\n]+)\n",
                "User%{SPACE}:%{SPACE}(?<User>[^\n]+)\n",
                "Action%{SPACE}:%{SPACE}(?<Action>[^\n]+)\n",
                "Source Type%{SPACE}:%{SPACE}(?<Source Type>[^\n]+)\n",
                "Source ID%{SPACE}:%{SPACE}(?<Source ID>[^\n]+)\n",
                "Appliance%{SPACE}:%{SPACE}(?<Appliance>[^\n]+)\n",
                "User-Agent%{SPACE}:%{SPACE}(?<User-Agent>[^\n]+)\n",
                "Role%{SPACE}:%{SPACE}(?<Role>[^\n]+)\n"
            ]
        }
    }

```

I would recommend against having spaces in your field names. Use [SourceType] rather than [Source Type].
