sqlserver数据库使用空间监控

数据库使用空间监控，并且每周发邮件预警，下面是操作步骤：

1：建立一张表

CREATE TABLE [_DBA].DBO.DB_USE_REPORT(server_name NVARCHAR(20),
database_name  NVARCHAR(20),    file_group  NVARCHAR(20),    logical_name  NVARCHAR(30),    physical_name  NVARCHAR(200),
type_desc NVARCHAR(20),    used_size_Mb int,    allocated_size_mb int,    max_size_Mb int,    growth int,    is_percent_growth int)
go
alter table [_DBA].DBO.DB_USE_REPORT  add inserttime  datetime default getdate()

2：在各个数据库每天收集一次数据

insert into [_DBA].DBO.DB_USE_REPORT
select @@SERVERNAME as server_name
,DB_NAME() as database_name
,case when data_space_id = 0 then 'LOG'
else FILEGROUP_NAME(data_space_id)
end as file_group
,name as logical_name
,physical_name
,type_desc
,FILEPROPERTY(name,'SpaceUsed')/128.0 as used_size_Mb
,size/128.0 as allocated_size_mb
,case when max_size = -1 then max_size
else max_size/128.0
end as max_size_Mb
,growth
,is_percent_growth,getdate()
from sys.database_files
where state_desc = 'ONLINE'

可以写成一个作业定时监控，每天定时插入数据。

3：创建存储过程发邮件出来每周report一次

USE [master]
GO

/****** Object:  StoredProcedure [dbo].[check_job_states]    Script Date: 2017/2/7 11:20:13 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE PROCEDURE [dbo].[check_db_use]

AS
BEGIN
DECLARE @tableHTML  NVARCHAR(MAX) ;
SET @tableHTML =
N'<H1>DB USED Report Last Week</H1>' +
N'<table border="1">' +
N'<tr><th>database_name</th><th>used_size_Mb</th>' +
N'<th>allocated_size_mb</th><th>type_desc</th><th>inserttime</th>' +
--N'<th>Expected Revenue</th></tr>' +
CAST ( (
SELECT  td =database_name     ,   '',
td =used_size_Mb ,   '',
td =allocated_size_mb,   '',
td =type_desc,   '',
td =inserttime   from [_DBA].DBO.DB_USE_REPORT  where inserttime> (getdate()-7) order by [database_name],type_desc,inserttime desc
FOR XML PATH('tr'), TYPE
) AS NVARCHAR(MAX) ) +
N'</table>' ;
EXEC msdb.dbo.sp_send_dbmail     @profile_name = 'sendmail',
@recipients='729975475@qq.com;',
@subject = 'DB USED Report Last Week',
@body = @tableHTML,
@body_format = 'HTML' ;
END
GO

然后创建一个定时作业直接每周report一次就好了。

邮件预警的效果图如下：
