I would like to display in a panel the lagtime between two times that come in a message. I have no idea how to initiate it and would appreciate some help: inDate "2014-03-18 05:00:00" outDate: "2014-03-18 05:05:00" lagtime = outdate - indate So what I would expect is lagtime to show average lagtime coming in for all. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

If you are referring to a Kibana panel, it sounds like you want something like the histogram panel, except you want a script to get the value instead of a field. The date histogram facet actually supports a value\_script computation, so you should be able to make a copy of Kibana histogram panel, and slightly modify the call to the date histogram facet to pass in your script into the value\_script field. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Thanks for your response but I am completely confused here: I am actually stuck on what the script would be. Technically I could put in a table format as well but the actual query is what I am unsure about; the script?

On this page: [http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-facets-date-histogram-facet.html#search-facets-date-histogram-facet](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-facets-date-histogram-facet.html#search-facets-date-histogram-facet) If you scroll down to the bottom, there is an example for value\_script. In your case, the value\_script would be something like (the result is in milliseconds, btw, so just convert accordingly if needed): doc['outDate'].value - doc['inDate'].value Again this is not supported by the Histogram Panel out of the box, but you can implement it yourself using a new panel, or by hacking the Histogram Panel. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
