If you are using COMMONAPACHELOG or COMBINEDAPACHELOG in your logstash config and you've not changed default type for "bytes" it was probably imported into elasticsearch as string instead of int
Elasticsearch cannot aggregate this data in such form. You'd can either modify "grok-patterns" file for your variable so bytes look like below or use mutate function in logstash to convert it to int (?:%{NUMBER:bytes:int}|-) regards m On Tuesday, 3 February 2015 16:31:12 UTC, Marcello A wrote: > > Hi All, > I'm trying to graph the usage of bandwidth fetched by Apache logs but > Kibana histogram doesn't graph any data.
