SQL Server 定时检查数据库服务器磁盘空间

查看磁盘空间的方法有很多，比如 Powershell,  WMIC 等，下面是用T-SQL的方法查看。对于多服务器，可以写游标，也可以在 Register Server 中建立一个组，比如 Production Group，QA Group 等等， 添加相应的服务器到不同的组中，最后在组的节点上应用下面的脚本即可。

create table #a (id int IDENTITY(1,1),DiskName varchar(50))

insert into #a(DiskName)

  exec xp_cmdshell  'wmic LOGICALDISK get name'

create table #b (id int IDENTITY(1,1),freespace varchar(50))

insert into #b(freespace)

  exec xp_cmdshell  'wmic LOGICALDISK get freespace'

create table #c (id int IDENTITY(1,1),size varchar(50))

insert into #c(size)

  exec xp_cmdshell  'wmic LOGICALDISK get size'

 

select server_name=@@servername,DiskName

,convert(bigint,replace(size,char(13),''))/1024/1024/1024 as total_disk_size_gb

,convert(bigint,replace(#b.freespace,char(13),''))/1024/1024/1024 as free_disk_size_gb

,convert(varchar,convert(decimal(4, 2),(convert(decimal(15, 2),convert(decimal(15, 2),replace(#b.freespace,char(13),''))/1024/1024/1024*100)/

convert(decimal(15, 2),convert(decimal(15, 2),replace(size,char(13),''))/1024/1024/1024))))+'%' as free_space_percent

from #a join #b on #a.id=#b.id join #c on #a.id=#c.id

where #a.id >1 and #b.freespace is not null and charindex(char(13),replace(#b.freespace,' ','')) <>1

 

drop table #a,#b,#c
