管理的SQL Server的数据库达100多个，最近想了解每个数据库的增量情况。

由于数据库分布在多台服务器中，首先需要收集数据库的空间使用情况，在前面做过磁盘空间的分析和收集，正好利用原有的一些Linked Server。原来有一张pubLinkServer表，对就的是服务器地址与Linked Server名。

pubLInkServer表：

CREATE TABLE [dbo].[pubLinkServer](
 [Id] [int] IDENTITY(1,1) NOT NULL,
 [LinkServerName] [varchar](50) ,
 [LinkServerIp] [varchar](20) ,
  [Status] [varchar](10) ,
 )
