We recently upgraded to ELK 5.1.2. Now we are seeing all field names in kibana discover getting automatically abbreviated to first letter for qualified names. For example, if the field name is name.first , it shows up as n.first.
This issue is even bigger when we use visualize section where drop down fields show n.f for name.first.
How do we retain the original field name in 5.1.2 version?
