Hi logstash users!

is it possible to catch all matches (global match) with a single regex?  
E.g. given the following text, which gets processed by `multiline` plugin first:

```auto
Caused by: a.b.c.Exception1: text1
Caused by: a.b.c.Exception2: text2

```

and the corresponding `grok` match:

```auto
grok {
	match => {
		"message" => "(?m)Caused by: (?<exception>[\w\.\$]+):\s+?(?<reason>[^\n]+)"
	}
}

```

Unfortunately it captures just the first match:

```auto
{
  "exception": [
    "a.b.c.Exception1"
  ],
  "reason": [
    "text1"
  ]
}

```

I'd like to have an array with both exceptions and text.

Is it possible at all?  
Thank you!
