I'm relatively new to working with ELK, and I haven't found a response to this question yet.
For storage optimization reasons, I want to use some aliases in my input files to store fixed values.
However I would like to display information in a pretty and readable format.
For instance, I have a field "status" in my dataset that can take 3 values: Civilian, Military and Student.
I would like to use some keys so I can store the information in a compact format, for instance:
1 => Civilian
2 => Military
3 => Student
How could I manage to then display the labelled information instead of the keys?
Thanks in advance,
