Hi All, Iam using logstash+elasticsearch+kibana3 in my local machine, having trouble to create histograms in Kibana3 with hostname & date wise logcount. i have gone through some of the articles, found the @timestamp type is having "date". i feel if i change to @timestamp type to string, hopefully i may meet my requirements. Please suggest how can i update following lines. [http://localhost:9200/\_mapping?pretty](http://localhost:9200/_mapping?pretty) "@timestamp" : { "type" : "date", "format" : "dateOptionalTime" }, Want to make it as "@timestamp" : { "type" : "string", }, also, let me know if we have any other way to meet my requirements. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
