Today I saw a strange behavior in Elasticsearch.
Yesterday I did this configuration:
This is my log:
I use this Grok:
But, today Elasticsearch changed the index's field type to "date", and now I have this message:
"Field Type Conflict: The type of this field changes across indices. It is unavailable for many analysis functions. The indices per type are as follows: "
Is it possible Elasticsearch change de index's field type automatically?
What I need to do in this case?
Thank you very much.
