I have this output plugin in Logstash to create elastic search index.
```auto
output {
amazon_es {
hosts => ["https://xxxxxxxxxxxxxxxx.es.amazonaws.com/"]
region => "ap-southeast-1"
index => "studentservice-logs-%{+YYYY.MM.dd}"
}
}
```
I want to update this index later because there will be some new fields added by _mutate_ for some log messages.
How to update index ?

hi @volcano,
this seems more like a logstash question, so I will move this question there
As for adding new fields: you should be able to add a new field to an index at any time. afaik, I don't think logstash prevents you from doing this.
The configuration you are showing is the actual output-index though (?) Do you mean to change the elasticsearch-index itself?

My Issue is :
I have added new fields in logstash.conf file by the mutate filter But these new fields are not visible in Kibana index pattern. I have already refreshed Kibana index pattern but still it is not visible.
what to look at to fix this issue ?

is the `_mapping` of your index correctly updated as well?
ie. run `GET localhost:9200/logstashindex/_mapping` in Kibana dev-tools or in browser.

hmmm... it seems your fields are not added to the elasticsearch index.
Can you look at an example document? e.g. just do an `_search` against the index. Does that document contain the expected fields?
If that document does not contain the expected fields,, something is going wrong in the ingestion process..

`_search` against the index
```
GET /service-logs-2020.01.05/_search
{
"query": {
"match_all" : { }
}
}
```
This does not also show new fields .
