sql server 运维时CPU,内存,操作系统等信息查询(

四:查看操作系统信息

--查看CPU的型号
EXEC xp_instance_regread
  'HKEY_LOCAL_MACHINE',
  'HARDWAREDESCRIPTIONSystemCentralProcessor',
  'ProcessorNameString';

有可能出现不同操作系统具有相同Version number值,例如Windows 7 和Windows Server 2008 R2的Version numberd都为6.1。导致下面查询结果出现多条记录(如下所示)。一般要酌情判断(如果生产服务器都为Windows服务器,可以剔除Windows XP、Windows 7这类数据)。

--查看内存信息
SELECT CEILING(total_physical_memory_kb * 1.0 / 1024 / 1024)  AS [物理内存大小]
    ,CAST(available_physical_memory_kb * 1.0 / 1024 / 1024
                       AS DECIMAL(8, 4)) AS [未使用的内存大小]
    ,CAST(( total_physical_memory_kb - available_physical_memory_kb ) * 1.0
    / 1024 / 1024 AS DECIMAL(8, 4))              AS [已使用的内存大小]
    ,CAST(system_cache_kb*1.0 / 1024/1024 AS DECIMAL(8, 4)) AS [系统缓存大小]
FROM  sys.dm_os_sys_memory

上面是通过sql语句查询,可以通过(这里是2014版)点击数据库-属性--可以看到很多信息,但是看不到物理内存和虚拟内存,一般在属性-内存-最大内存设置:物理内存的80%

--查询每个磁盘的信息,包括已经使用的和未使用的信息
SET NOCOUNT ON
DECLARE @Result   INT;
DECLARE @objectInfo   INT;
DECLARE @DriveInfo   CHAR(1);
DECLARE @TotalSize   VARCHAR(20);
DECLARE @OutDrive   INT;
DECLARE @UnitMB   BIGINT;
DECLARE @FreeRat   FLOAT;
SET @UnitMB = 1048576;
--创建临时表保存服务器磁盘容量信息
CREATE TABLE #DiskCapacity
(
[DiskCD]   CHAR(1) ,
FreeSize   INT   ,
TotalSize   INT
);
INSERT #DiskCapacity([DiskCD], FreeSize )
EXEC master.dbo.xp_fixeddrives;
EXEC sp_configure 'show advanced options', 1
RECONFIGURE WITH OVERRIDE;
EXEC sp_configure 'Ole Automation Procedures', 1;
RECONFIGURE WITH OVERRIDE;
EXEC @Result = master.sys.sp_OACreate 'Scripting.FileSystemObject',@objectInfo OUT;
DECLARE CR_DiskInfo CURSOR LOCAL FAST_FORWARD
FOR
SELECT DiskCD FROM #DiskCapacity
ORDER by DiskCD
OPEN CR_DiskInfo;
FETCH NEXT FROM CR_DiskInfo INTO @DriveInfo
WHILE @@FETCH_STATUS=0
BEGIN
EXEC @Result = sp_OAMethod @objectInfo,'GetDrive', @OutDrive OUT, @DriveInfo
EXEC @Result = sp_OAGetProperty @OutDrive,'TotalSize', @TotalSize OUT
UPDATE #DiskCapacity
SET TotalSize=@TotalSize/@UnitMB
WHERE DiskCD=@DriveInfo
FETCH NEXT FROM CR_DiskInfo INTO @DriveInfo
END
CLOSE CR_DiskInfo
DEALLOCATE CR_DiskInfo;
EXEC @Result=sp_OADestroy @objectInfo
EXEC sp_configure 'show advanced options', 1
RECONFIGURE WITH OVERRIDE;
EXEC sp_configure 'Ole Automation Procedures', 0;
RECONFIGURE WITH OVERRIDE;
EXEC sp_configure 'show advanced options', 0
RECONFIGURE WITH OVERRIDE;
SELECT DiskCD   AS [Drive CD]   ,
  STR(TotalSize*1.0/1024,6,2)   AS [Total Size(GB)] ,
  STR((TotalSize - FreeSize)*1.0/1024,6,2)   AS [Used Space(GB)] ,
  STR(FreeSize*1.0/1024,6,2)   AS [Free Space(GB)] ,
  STR(( TotalSize - FreeSize)*1.0/(TotalSize)* 100.0,6,2) AS [Used Rate(%)]  ,
  STR(( FreeSize * 1.0/ ( TotalSize ) ) * 100.0,6,2)    AS [Free Rate(%)]
FROM #DiskCapacity;
DROP TABLE #DiskCapacity;

三:查看数据库服务器硬盘的信息


使用SQL语句获得服务器名称和IP地址 获取服务器名称:


通过下面SQL语句,我们可以查看操作系统版本、补丁、语言等信息
--创建临时表保存语言版本信息
CREATE TABLE #Language
(
[LanguageDtl] NVARCHAR(64) ,
[os_language_version] INT
);
INSERT INTO #Language
SELECT 'English - United States' ,1033 UNION ALL
SELECT 'English - United Kingdom' ,2057 UNION ALL
SELECT 'Chinese - People''s Republic of China',2052 UNION ALL
SELECT 'Chinese - Singapore' ,4100 UNION ALL
SELECT 'Chinese - Taiwan' ,1028 UNION ALL
SELECT 'Chinese - Hong Kong SAR' ,3076 UNION ALL
SELECT 'Chinese - Macao SAR' ,5124;
WITH SystemVersion(SystemInfo,ReleaseNo)
AS
(
SELECT 'Windows 10' ,
'10.0*'
UNION ALL
SELECT 'Windows Server 2016 Technical Preview' ,
'10.0*'
UNION ALL
SELECT 'Windows 8.1' ,
'6.3*'
UNION ALL
SELECT 'Windows Server 2012 R2' ,
'6.3'
UNION ALL
SELECT 'Windows 8' ,
'6.2'
UNION ALL
SELECT 'Windows Server 2012' ,
'6.2'
UNION ALL
SELECT 'Windows 7' ,
'6.1'
UNION ALL
SELECT 'Windows Server 2008 R2' ,
'6.1'
UNION ALL
SELECT 'Windows Server 2008' ,
'6.0'
UNION ALL
SELECT 'Windows Vista' ,
'6.0'
UNION ALL
SELECT 'Windows Server 2003 R2' ,
'5.2'
UNION ALL
SELECT 'Windows Server 2003' ,
'5.2'
UNION ALL
SELECT 'Windows XP 64-Bit Edition' ,
'5.2'
UNION ALL
SELECT 'Windows XP' ,
'5.1'
UNION ALL
SELECT 'Windows 2000' ,
'5.0'
)
SELECT s.SystemInfo
,w.windows_service_pack_level
,l.LanguageDtl
FROM sys.dm_os_windows_info w
INNER JOIN SystemVersion s ON w.windows_release=s.ReleaseNo
INNER JOIN #Language l ON l.os_language_version = w.os_language_version;
DROP TABLE #Language

获取IP地址可以使用xp_cmdshell执行ipconfig命令;
--开启xp_cmdshell
exec sp_configure'show advanced options', 1
reconfigure with override
exec sp_configure'xp_cmdshell', 1
reconfigure with override
exec sp_configure'show advanced options', 0
reconfigure with override
go
begin
declare @ipline varchar(200)
declare @pos int
declare @ip varchar(40)
set nocount on
set @ip = null
if object_id('tempdb..#temp') is not null drop table #temp
create table #temp(ipline varchar(200))
insert #temp exec master..xp_cmdshell'ipconfig'
select @ipline = ipline
from #temp
where upper(ipline) like '%IPv4 地址%'--这里需要注意一下,系统不同这里的匹配值就不同
if @ipline is not null
begin
set @pos = charindex(':',@ipline,1);
set @ip = rtrim(ltrim(substring(@ipline ,
@pos + 1 ,
len(@ipline) - @pos)))
end
select distinct(rtrim(ltrim(substring(@ipline ,
@pos + 1 ,
len(@ipline) - @pos)))) as ipaddress from #temp
drop table #temp
set nocount off
end
go

如下所示,我们可以通过下面脚本获取服务器的各个磁盘的使用情况。但是无法获取磁盘的型号、转速之类的信息。
SET NOCOUNT ON
DECLARE @Result INT;
DECLARE @objectInfo INT;
DECLARE @DriveInfo CHAR(1);
DECLARE @TotalSize VARCHAR(20);
DECLARE @OutDrive INT;
DECLARE @UnitMB BIGINT;
DECLARE @FreeRat FLOAT;
SET @UnitMB = 1048576;
--创建临时表保存服务器磁盘容量信息
CREATE TABLE #DiskCapacity
(
[DiskCD] CHAR(1) ,
FreeSize INT ,
TotalSize INT
);
INSERT #DiskCapacity([DiskCD], FreeSize )
EXEC master.dbo.xp_fixeddrives;
EXEC sp_configure 'show advanced options', 1
RECONFIGURE WITH OVERRIDE;
EXEC sp_configure 'Ole Automation Procedures', 1;
RECONFIGURE WITH OVERRIDE;
EXEC @Result = master.sys.sp_OACreate 'Scripting.FileSystemObject',@objectInfo OUT;
DECLARE CR_DiskInfo CURSOR LOCAL FAST_FORWARD
FOR
SELECT DiskCD FROM #DiskCapacity
ORDER by DiskCD
OPEN CR_DiskInfo;
FETCH NEXT FROM CR_DiskInfo INTO @DriveInfo
WHILE @@FETCH_STATUS=0
BEGIN
EXEC @Result = sp_OAMethod @objectInfo,'GetDrive', @OutDrive OUT, @DriveInfo
EXEC @Result = sp_OAGetProperty @OutDrive,'TotalSize', @TotalSize OUT
UPDATE #DiskCapacity
SET TotalSize=@TotalSize/@UnitMB
WHERE DiskCD=@DriveInfo
FETCH NEXT FROM CR_DiskInfo INTO @DriveInfo
END
CLOSE CR_DiskInfo
DEALLOCATE CR_DiskInfo;
EXEC @Result=sp_OADestroy @objectInfo
EXEC sp_configure 'show advanced options', 1
RECONFIGURE WITH OVERRIDE;
EXEC sp_configure 'Ole Automation Procedures', 0;
RECONFIGURE WITH OVERRIDE;
EXEC sp_configure 'show advanced options', 0
RECONFIGURE WITH OVERRIDE;
SELECT DiskCD AS [Drive CD] ,
STR(TotalSize*1.0/1024,6,2) AS [Total Size(GB)] ,
STR((TotalSize - FreeSize)*1.0/1024,6,2) AS [Used Space(GB)] ,
STR(FreeSize*1.0/1024,6,2) AS [Free Space(GB)] ,
STR(( TotalSize - FreeSize)*1.0/(TotalSize)* 100.0,6,2) AS [Used Rate(%)] ,
STR(( FreeSize * 1.0/ ( TotalSize ) ) * 100.0,6,2) AS [Free Rate(%)]
FROM #DiskCapacity;
DROP TABLE #DiskCapacity

SELECT SERVERPROPERTY('MachineName')
select @@SERVERNAME
select HOST_NAME()

2:在老外博客中看到一个计算CPU相关信息的SQL,不过虚拟机计算有点小问题
DECLARE @xp_msver TABLE (
[idx] [int] NULL
,[c_name] [varchar](100) NULL
,[int_val] [float] NULL
,[c_val] [varchar](128) NULL
)
INSERT INTO @xp_msver
EXEC ('[master]..[xp_msver]');;
WITH [ProcessorInfo]
AS (
SELECT ([cpu_count] / [hyperthread_ratio]) AS [number_of_physical_cpus]
,CASE
WHEN hyperthread_ratio = cpu_count
THEN cpu_count
ELSE (([cpu_count] - [hyperthread_ratio]) / ([cpu_count] / [hyperthread_ratio]))
END AS [number_of_cores_per_cpu]
,CASE
WHEN hyperthread_ratio = cpu_count
THEN cpu_count
ELSE ([cpu_count] / [hyperthread_ratio]) * (([cpu_count] - [hyperthread_ratio]) / ([cpu_count] / [hyperthread_ratio]))
END AS [total_number_of_cores]
,[cpu_count] AS [number_of_virtual_cpus]
,(
SELECT [c_val]
FROM @xp_msver
WHERE [c_name] = 'Platform'
) AS [cpu_category]
FROM [sys].[dm_os_sys_info]
)
SELECT [number_of_physical_cpus]
,[number_of_cores_per_cpu]
,[total_number_of_cores]
,[number_of_virtual_cpus]
,LTRIM(RIGHT([cpu_category], CHARINDEX('x', [cpu_category]) - 1)) AS [cpu_category]
FROM [ProcessorInfo]
---查看虚拟机CPU信息
DECLARE @xp_msver TABLE (
[idx] [int] NULL
,[c_name] [varchar](100) NULL
,[int_val] [float] NULL
,[c_val] [varchar](128) NULL
)
INSERT INTO @xp_msver
EXEC ('[master]..[xp_msver]');;
WITH [ProcessorInfo]
AS (
SELECT ([cpu_count] / [hyperthread_ratio]) AS [number_of_physical_cpus]
,[hyperthread_ratio] AS [number_of_cores_per_cpu]
,[cpu_count] AS [total_number_of_cores]
,[cpu_count] AS [number_of_virtual_cpus]
,(
SELECT [c_val]
FROM @xp_msver
WHERE [c_name] = 'Platform'
) AS [cpu_category]
FROM [sys].[dm_os_sys_info]
)
SELECT [number_of_physical_cpus]
,[number_of_cores_per_cpu]
,[total_number_of_cores]
,[number_of_virtual_cpus]
,LTRIM(RIGHT([cpu_category], CHARINDEX('x', [cpu_category]) - 1)) AS [cpu_category]
FROM [ProcessorInfo]

(3)适用于SQL Server 2012 到 SQL Server 2014
SELECT CEILING(physical_memory_kb*1.0/1024/1024) AS [Physical Memory Size]
FROM sys.dm_os_sys_info OPTION (RECOMPILE);
