Ada tiga DMV yang dapat Anda gunakan untuk melacak penggunaan tempdb:
Dua yang pertama akan memungkinkan Anda untuk melacak alokasi di tingkat kueri & sesi. Trek ketiga alokasi di seluruh versi menyimpan, pengguna dan objek internal.
Kueri contoh berikut akan memberi Anda alokasi per sesi:
SELECT
sys.dm_exec_sessions.session_id AS [SESSION ID]
,DB_NAME(database_id) AS [DATABASE Name]
,HOST_NAME AS [System Name]
,program_name AS [Program Name]
,login_name AS [USER Name]
,status
,cpu_time AS [CPU TIME (in milisec)]
,total_scheduled_time AS [Total Scheduled TIME (in milisec)]
,total_elapsed_time AS [Elapsed TIME (in milisec)]
,(memory_usage * 8) AS [Memory USAGE (in KB)]
,(user_objects_alloc_page_count * 8) AS [SPACE Allocated FOR USER Objects (in KB)]
,(user_objects_dealloc_page_count * 8) AS [SPACE Deallocated FOR USER Objects (in KB)]
,(internal_objects_alloc_page_count * 8) AS [SPACE Allocated FOR Internal Objects (in KB)]
,(internal_objects_dealloc_page_count * 8) AS [SPACE Deallocated FOR Internal Objects (in KB)]
,CASE is_user_process
WHEN 1 THEN 'user session'
WHEN 0 THEN 'system session'
END AS [SESSION Type], row_count AS [ROW COUNT]
FROM
sys.dm_db_session_space_usage
INNER join
sys.dm_exec_sessions
ON sys.dm_db_session_space_usage.session_id = sys.dm_exec_sessions.session_id
Jika Anda ingin melacak penggunaan selama periode waktu tertentu, pertimbangkan untuk mengumpulkan data dengan sp_whoisactive , seperti yang ditunjukkan oleh Kendra Little .
