I am trying to understand how to get access to fields that I told Logstash to parse out of log messages for me.

In the data shown below there is a field under \_host called log\_level. How do I get a hold of that in Kibana? I can see it on the Discover tab. But when I go to the Visualize tab I dont see it. I can see it in the mapping for my index. I assume I missing some step that tells Kibana to use the field in aggregations.

Part of the mapping that shows the field is there.

```
      "log_level" : {
        "type" : "keyword",
        "ignore_above" : 1024
      },

```

Hi @swright-eti,

Can you try refresh the Kibana mapping cache in `Management -> Index Patterns`? Choose your index pattern and press "Refresh field list" button (top right corner, near the `Delete` button).

Best,  
Oleg
