I have some data that I'd like to do a regex of a field and then an aggregation (count)
of the results of that regex'd field. For instance:
Data:
GET system/path_param/1234567/00?query_param=xpto HTTP/1.1
GET system/path_param/8901234/00?query_param=xpto HTTP/1.1
GET system/path_param/5678901/00?query_param=xpto HTTP/1.1
GET other_url/other_path_param/abcde HTTP/1.1
Aggregation:
system/path_param:3
other_url/other_path_param: 1
Considering that I already have the query that brings me the data, how to do this aggregation in Kibana?
