How to show data in tabular form without aggregation in kibana 4?

I am trying to show number of servers down currently in kibana.

As for any server whose uptime is 1/1/1970 it is down. Is it possible to show data in this form? Also can I view servers down from certain time like 15 minutes ?

From discovery tab, create a search, select the columns you want & save. Head over to your Dashboard tab and add a visualization - pick your saved search. This will show up as a table.
