Hi,

I have an ansible dictionary where I define all my logfiles to parse and what it the format of the message:

logstash.conf

```auto
grok {
  match => [
"message", '%{SYSLOGTIMESTAMP:timestamp} %{SYSLOGHOST:dockerhost} %{DATA:conteneur}(?:\[%{POSINT:pid}\])( time="%{TIMESTAMP_ISO8601:logtime}")?( level=%{LOGLEVEL:severity})?( msg=)?%{GREEDYDATA:message}'
  ],
"message", '%{SYSLOGTIMESTAMP:timestamp} %{SYSLOGHOST:dockerhost} %{DATA:conteneur}'
  ],
}

```

Don't focus on the syntax, because I still don't work on differents formats that message will have, it is just an example.

I get it from logstash.conf.j2

```auto
  grok {
    match => [
    {% for log in filebeat_dict.filebeat.logs | default([]) %}
      "message" => "{{ log.format }}",
    {% endfor %}
    ]
  }

```

Here is my ansible dictionary:

```auto
logs:
      - path: "/var/log/docker"
        app_id: "docker"
        format: '%{SYSLOGTIMESTAMP:timestamp} %{SYSLOGHOST:dockerhost} %{DATA:conteneur}(?:\[%{POSINT:pid}\])?:?:( time="%{TIMESTAMP_ISO8601:logtime}")?( level=%{LOGLEVEL:severity})?( msg=)?%{GREEDYDATA:message}'
      - path: "/data/nexus/data/log"
        app_id: "nexus"
        format: '%{SYSLOGTIMESTAMP:timestamp} %{SYSLOGHOST:dockerhost} %{DATA:conteneur}'

```

I have 2 questions for that:

- Is it the correct approach ?
- For the last line, I will always have a last comma that make logstash fail. How should I get rid of the last comma ???

Thanks for your help!
