We have added some documents in the elasticsearch which had superfluent fields (a lot). The specific documents have been deleted, but the dynamic field mappings from kibana remain, even after recreating the index-pattern.
Is there any possiblity to drop the fields from kibana that do not longer exist in elasticsearch?
Kibana version: 4.4.2
Elasticsearch version: 2.2.0
Go to settings in kibana, and press the refresh button, now you will get the up to date fields

I have created an index-patter in kibana (7.11) in the UI and i can see all the fields configured correctly. But when i go to Saved objects and export it, it doesn't contain any fields
{"attributes":{"fieldAttrs":"{}","fields":"[]"...
Is there something i am missing here?
I have another index-pattern created by journalbeat which exports correctly with all the configured fields.
Thanks
I have faced the same issue. Starting Kibana 7.11, index patterns as saved object contain no more field detail. The list of field is prepared on load.
Elastic added a changelog entry here finally:
In index pattern management - Refresh button removed as index pattern field lists are refreshed when index patterns are loaded, such as on page load or when moving between kibana apps
I have elasticsearch mapping which lists a field but when trying to visualize in kibana it doesnt list that field. Moreover i can see that field under 'popular' section of Discover page.
i see some note like:
"This field is present in your elasticsearch mapping but not in any documents in the search results. You may still be able to visualize or search on it."
What does this mean and how can i visualize a mapped field.
It's mean that you have a mapping but you don't have documents, you don't have data,so you need to index data to elasticsearch index
Kibana's UI allows the user to create a scripted field which is stored as part of the index (screenshot below). How can that be done programatically? In particular, using either the NEST client or the Elasticsearch low level client.

Note that I am not asking how to create add an expression/script field as part of a query, I'm specifically looking for how to add it as part of the Index when the mapping is created so that queries can reference it without having to explicitly include it.
Kibana dashboards are stored in the .kibana index. To export dashboards, you can query the Kibana index as you would any other index. For example, curl -XGET http://localhost:9200/.kibana/_search?type=dashboard&pretty would show the JSON for your dashboards. You could export the template, add the scripted field to the JSON, and then POST it again. Since Kibana uses a standard Elasticsearch index, the normal Elasticsearch API would apply to modifying Kibana dashboards. This may provide a little more clarification.
At the time of writing, current version 5.2 does not have an official way to do this.
This is how I do it:
Get index fields: GET /.kibana/index-pattern/YOUR_INDEX
Add your scripted field to _source.fields (as string, notice scaped quotation marks)
"fields":"[...,{\"name\":\"test\",\"type\":\"number\",\"count\":0,\"scripted\":true,\"script\":\"doc['area_id'].value\",\"lang\":\"painless\",\"indexed\":false,\"analyzed\":false,\"doc_values\":false,\"searchable\":true,\"aggregatable\":true}]"
Post back _source json to /.kibana/index-pattern/YOUR_INDEX
{
"title":"YOUR_INDEX",
"timeFieldName":"time",
"fields":"[...,{\"name\":\"test\",...}]"
}
I am exploring ELK stack and coming across an issue.
I have generated logs, forwarded the logs to logstash, logs are in JSON format so they are pushed directly into ES with only JSON filter in Logstash config, connected and started Kibana pointing to the ES.
Logstash Config:
filter {
json {
source => "message"
}
Now I have indexes created for each day's log and Kibana happily shows all of the logs from all indexes.
My issue is: there are many fields in logs which are not enabled/indexed for filtering in Kibana. When I try to add them to the filer in Kibana, it says "unindexed fields cannot be searched".
Note: these are not sys/apache log. There are custom logs in JSON format.
Log format:
{"message":"ResponseDetails","#version":"1","#timestamp":"2015-05-23T03:18:51.782Z","type":"myGateway","file":"/tmp/myGatewayy.logstash","host":"localhost","offset":"1072","data":"text/javascript","statusCode":200,"correlationId":"a017db4ebf411edd3a79c6f86a3c0c2f","docType":"myGateway","level":"info","timestamp":"2015-05-23T03:15:58.796Z"}
fields like 'statusCode', 'correlationId' are not getting indexed. Any reason why?
Do I need to give a Mapping file to ES to ask it to index either all or given fields?
You've updated the Kibana field list?
Kibana.
Settings.
Reload field list.
Newer version:
Kibana.
Management.
Refresh icon on the top right.
As of 6.4.0:
The warning description puts it very simply:
Management > Index Patterns > Select your Index > Press the refresh button in the top right corner.
If you try to refresh and you can't solve it try to change index.blocks.write: "false"

I have Kibana 4.0.1 running on top of elasticsearch 1.4.4. It was very smooth and virtually had no setup time. Suddenly I have run into a problem.
If I add a new field in my elasticsearch index, it's not visible in fields section. I can still query on that field in discover section. But, I can't make a graph based on the new field as it's not visible in fields list.
Kibana apparently fetches _mapping at the time of setup and stores it in elasticsearch index named .kibana. Once done, it never changes that. Deleting this index should load fresh _mapping from elasticsearch. But I don't want to lose all the saved dashboards and visualizations.
Is there a was to force Kibana to load fresh mapping at regular interval?
Yes in the settings tab you can refresh the index. Check the yellow refresh botton in the image below.
