通过T-SQL获得连接客户端的IP和机器名
/******************************************下面的SP是返回所有的客户端的IP和HOSTNAME,目的是可以通过JOB返回某一时间点的CLIENT 的连接情况.
我当时写这个脚本的目的是经常有一些没有授权的客户机,通过SQLSERVER的CLIENT就连接到SQLSERVER,所以我可以定义一个JOB每隔30分钟运行一次这个存储过程,并且将内容写的一个LOG文件,这样可以大概记录有哪些CLIENT在连接SQLSERVER,当然大家可以可以修改这个脚本,使之返回更多的信息,比如CPU,MEMORY,LOCK....
