hi all.
I have defined a new field by the grok filter and i see it in the Discovery section, but i don't see it in the field list for visualization by a linear chart and sum aggregation function. how can i resolved it?
Thanks
You may need to go to Index Pattern management and refresh the index pattern relating to the field.
thanks. Your suggestion was made But it didn't work.by using a scripted field (doc['num_extract'].value;) this problem solved.
