The pattern you have configured does not match your data. The first field is not a pure IP address, but also seems to contain a port number, which you will need to account for. Have a look [at this introductory blog post](https://www.elastic.co/blog/a-practical-introduction-to-logstash) which shows you how to work with Logstash and develop grok patterns.
