SQL语句实现查询SQL Server内存使用状况

<div class="jb51code">
<pre class="brush:sql;">
SELECT type,--Clerk的类型
sum(virtual_memory_reserved_kb)as vm_Reserved_kb,--保留的内存
sum(virtual_memory_committed_kb)as vm_Committed_kb,--提交的内存
sum(awe_allocated_kb)as awe_Allocated_kb,--开启AWE后使用的内存
sum(shared_memory_reserved_kb)as sm_Reserved_kb,--共享的保留内存
sum(shared_memory_committed_kb)as sm_Committed_kb,--共享的提交内存
sum(single_pages_kb)as SinlgePage_kb,-- Buffer Pool中的Stolen的内存
sum(multi_pages_kb)as MultiPage_kb-- MemToLeave的内存
FROM sys.dm_os_memory_clerks
GROUP BY type ORDER BYtype

--查询Buffer Pool/Memory To Leave
SELECT
sum(virtual_memory_reserved_kb)AS [Reserved],sum(virtual_memory_committed_kb)AS [Commit],sum(virtual_memory_reserved_kb)/sum(virtual_memory_committed_kb) AS[Reserved/Commit],sum(single_pages_kb)+sum(multi_pages_kb) AS [Stolen],sum(virtual_memory_committed_kb)+sum(single_pages_kb)AS [Buffer Pool],sum(multi_pages_kb) AS[MemToLeave],SUM(awe_allocated_kb)AS [AWEAllocated]
FROM sys.dm_os_memory_clerks

--查询SQLSERVER内存使用

select * from sys.dm_os_process_memory
