Hi

If you extracted those fields by eval, its not gonna work as there is a sequence in search time operations. - field alias comes before eval ( calculated fields)

Please take a look at this sequence of search time operation, which means every search ran in UI go through these operations in order.

Thanks for your answer, but I use inline extraction which is in the firest sequnece , that field alias work on some indexes and don't work on the others.

Does that means you have Extract-classname in props of searchhead for above extracted fields?

Thanks

The field alias is set at sourcetype/source/host level. Where have you setup your field alias and did you use correct sourcetype/source/host?
