That is just the internal Kibana index. If that is all you see, you have no data in the cluster to visualise, so you will not be able to define any index pattern in Kibana as no mappings for that pattern can be found.
If you index some data and are able to see some other index when you run _cat/shards you should be able to create an index pattern and explore that data.
You will need to index them into Elasticsearch. For this you can use Filebeat and/or Logstash. The Logstash config you provided in your initial post seem to be taken from some outdated guide, as the options have since changed, so it is better to start based on the official documentation.
You had a Logstash config in your first post, where I pointed out some errors in the Elasticsearch output section. This seems to be a good starting point. Have you had a look at the documentation? What have you tried since? Where are you having issues?
As you see I corrected Elasticsearch config and posted it here. About Logstash, I removed my config and used default config of Logstash but not worked.
I don't know what is my problem is
