Graphing NetFlow data in Kibana 3


(Ryan Melena) #1

Hey all,

I've got LogStash working nicely with the NetFlow codechttp://logstash.net/docs/1.2.1/codecs/netflowbut I'm running into problems trying to graph the results in Kibana 3.

When I create a Histogram Panel and try to graph the "netflow.in_bytes"
field I get the following error:

ClassCastException[org.elasticsearch.index.fielddata.plain.PagedBytesIndexFieldData
cannot be cast to org.elasticsearch.index.fielddata.IndexNumericFieldData]

It seems that ElasticSearch isn't recognizing the PagedBytesIndexFieldData
type as being numeric. Is this intended? If so, is there something I
should be doing differently to be able to graph this data in Kibana 3?

Thanks,
Ryan
