I am trying to create pie chart for Apache logs, I have passed logs through logstash and could see server_response field which I created to see the response status for visited sites. I am not able to find server_response field under visualization while using the histogram to prepare 200 response code graph.
Can you please let me know how I can see server_response field under visualization, I can add the same field while running search on discover.
I tried creating scripting field from Kibana as doc[server.response].value. It starts reflected under visualization but I am getting error in elastic search.
No field found for [server_response] in mapping with types
