Frequently Querying the DMV - sys.dm_exec_sessions, sys.dm_exec_connections and sys.dm_exec_requests
Could frequently (e.g. 5 seconds) querying the below DMVs from a custom tool to get the connection info impact performance on SQL server? I understand this would give a snapshot at that point.
SQL audit logs probably the best way to get this info but It would help if I get any guidance based on your experience with the DMV.
select sys.dm_exec_sessions.session_id, host_name as [Connecting machine name], client_net_address AS [Connecting machine IP],
program_name,client_interface_name,login_name,nt_domain,nt_user_name, name as DatabaseName,
sys.dm_exec_sessions.status AS [Session status],command,r.Status AS [Request Status],
last_request_start_time,last_request_end_time,sys.dm_exec_sessions.status,r.status, text, *
from sys.dm_exec_sessions inner join sys.dm_exec_connections on sys.dm_exec_sessions.session_id = sys.dm_exec_connections.session_id
inner join sys.dm_exec_requests r on sys.dm_exec_connections.connection_id = r.connection_id
inner join sys.databases on r.database_id = sys.databases.database_id
cross apply sys.dm_exec_sql_text(r.sql_handle)
