How to filter from terms Aggregation

Hi Team,
I need to create visualization 's for metricbeat cpu ,memory,filesystem utilizations for 10 servers. I want filter few servers from beat.name using term aggregation.
when i filter out with terms aggregation as beat.name it is showing data for all servers,but i want data for particular servers.

Kindly provide me the solution to filter particular servers.

You need to use beat.hostname to split by different server.
