Good day everyone!

I'm using filebeat and logstash.

Here is the part of logstash filter which is not working as I'm expecting.

```
if "app_name" in [tags] {

mutate {
    gsub => ["message", "\x1B\[([0-9]{1,2}(;[0-9]{1,2})?)?[m|K]", ""]
  }

  grok {
     match => [
                "source" => "/opt/data/app/logs/%{GREEDYDATA:service_name}/%{GREEDYDATA:log_file_name}",
                "message" => "\[%{GREEDYDATA:severity}\] %{TIMESTAMP_ISO8601:timestamp} - %{GREEDYDATA:message}"
              ]
       overwrite => ["message"]
       }

  date {
    match => ["timestamp", "yyyy-mm-dd HH:mm:ss"]
    target => "@timestamp"
    timezone => "UTC"
    remove_field => ["timestamp"]
  }
}

```

As you can see, I'm trying to match and extract values from "source" field and "message" field in the same grok. But works only the first one (in this example - "source").

Is there a way how to achieve that?

Any help will be extremely appreciated!

By default, Grok stop after the first match successful, which mean that if first parsing is successful (_source_), _message_ parsing will not be 'invoqued'.

To allow it to match your multiple fields / formats, you will need to disable the option [break\_on\_match](https://www.elastic.co/guide/en/logstash/current/plugins-filters-grok.html#plugins-filters-grok-break_on_match)
