Determine the server that sent a query For the distributed queries, is it possible to determine the server that sent a query?

For example, I have stats:


SELECT DB_NAME(st.dbid),
       text,
       request_time,
       query_plan,
       (requested_memory_kb / 1024),
       (granted_memory_kb / 1024),
       query_cost
FROM sys.dm_exec_query_memory_grants AS mg
CROSS APPLY sys.dm_exec_sql_text(mg.sql_handle) AS st
CROSS APPLY sys.dm_exec_query_plan(mg.plan_handle) AS ph
ORDER BY requested_memory_kb DESC


How can I get server that sent each query? What tables should I join or functions to apply?
The DMV sys.dm_exec_sessions has column host_name which is the computer at the client end of the connection.  You can join that to your posted query through the session_id.
