I have a custom format of nginx `access.log` and I want to parse it with `logstash`.

The format of the access log is the following:

```auto
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
                  '$status $body_bytes_sent "$http_referer" '
                  '"$http_user_agent" "$http_x_forwarded_for" ';

```

I was not able to find what kind of `grok match pattern` to use. Any idea of how can I deal with it?
