Hi All, I'm trying to graph the usage of bandwidth fetched by Apache logs but Kibana histogram doesn't graph any data. Could someone help me to use correctly the histogram panel?

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.

Thanks for the tips 🙂 I prefer to change the configuration file because the file patternss grok-pattern can change with the RPM updates. I added this part ``` mutate { convert => ["bytes", "integer"] } ``` } Marcello Il giorno martedì 3 febbraio 2015 18:54:02 UTC+1, Marcin izo ha scritto: > 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.
