Create panel to display latency time using two datetime fields

Elastic Stack Elasticsearch
1

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.

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.

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

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.
