Logstash Aggregation

Hello,

I would like to know how to create an index from an existing Index with Elasticsearch aggregations. (In my case, i would like to get statistics per login: count_connection, distinct_count_connection, first_connection, last_connection in new index or csv output).

I use ELK 5.4

Thank you in advance

Rather than Logstash, you're probably better off asking in the Elasticsearch forum about how to use the Reindex API to do this with a query in the reindex API call.

Thanks for reply. Reindex API it's only for dump current index into new Index.
In index 1 I've all data connections per day, and I would like to create an index 2 from aggregations of Index 1 (one line per login "email", with all informations "count connection, date last connexion, .....")

You should re-read the link I sent you. The Reindex API, while it can "dump" an index into a new one, it's much more sophisticated than just that use case. It also allows you to use the results of a query to populate a new index:

POST _reindex
{
  "source": {
    "index": "twitter",
    "type": "tweet",
    "query": {
      "term": {
        "user": "kimchy"
      }
    }
  },
  "dest": {
    "index": "new_twitter"
  }
}

So, why not try aggregations in a reindex with a query?

Could you please give me an example of query syntax with aggs inside query?

That question definitely belongs in the Elasticsearch section of the forums.
