 TempDB usage details that you can use for monitoring or troubleshooting in SQL Server. I’ll include the most common DMV queries and what each one tells you. 🔍 TempDB Usage – Key Details & Diagnostic Queries 1. TempDB Space Usage (By File) Shows how much space is used/free in each TempDB data file. SQLSELECT    name AS FileName,    size/128 AS TotalMB,    CAST(FILEPROPERTY(name, 'SpaceUsed') AS INT)/128 AS UsedMB,    (size - FILEPROPERTY(name, 'SpaceUsed'))/128 AS FreeMBFROM tempdb.sys.database_files;Show more lines 2. TempDB Usage by Session Helps identify which sessions are consuming TempDB. SQLSELECT     session_id,    user_objects_alloc_page_count AS UserAllocatedPages,    internal_objects_alloc_page_count AS InternalAllocatedPages,    user_objects_dealloc_page_count AS UserDeallocatedPages,    internal_objects_dealloc_page_count AS InternalDeallocatedPagesFROM sys.dm_db_session_...
