Hi,
I load data from a rest api to elasticsearch via logstash.
first i create my index 'bookings'with mapping then i load the data using logstash.
the problem is when i view the datain discover i get error in the data type .
for example 'idhotel': 125478 ... in discover it is displayed 'idhotel: 125,478
ps: in the mapping I put 'idhotel' of type integer
any help please !

Hi @hiba
You can change the display-format of a field-value using field-formatters of the index pattern. [https://www.elastic.co/guide/en/kibana/current/field-formatters-numeric.html](https://www.elastic.co/guide/en/kibana/current/field-formatters-numeric.html) (go to "Management"\>"Index pattern"-\> select your `bookings` index pattern)
You probably just want `String` formatter instead of the default.
