Hi everyone,
I am able to see the raw data which is coming from elasticsearch through logstash, same thing when I am trying to get the data from elasticsearch through fulentd, then I am not able to see the raw data, whereas i have created enough charts for the data which was coming from elasticsearch through fluentD.
Use table panel, then in the metric type dropdown select “Raw Document”
I have tried that @torkel. 
When I tried I got this error.
failed to parse search source. unknown search element [docvalue_fields]
what version of Elasticsearch do you have? Have you specified the version in data source settings ?
thank you @torkel. as you said the problem was with the version specified. changed to ES2X it worked.
