I have renamed the field in logstash using mutate filter.
When a plot histogram, elastic search says field not found as below
"Caused by: org.elasticsearch.search.facet.FacetPhaseExecutionException: Facet : (value) field [HeapUsed] not found".
"HeapUsed" is my renamed field.
Do i have to create a new field in elastic search mapping template for renamed field?
