监控-CPU使用率

原始脚本来自TG，自己对部分脚本做了调整，分享出来仅供参考，请勿整篇Copy！

如果一个服务器上有多个实例，不知道得出来的数据是服务器整体的，还是单个实例的数据。
数据库服务器收集本地数据，然后使用SSIS汇集监控数据，目标服务器使用以下语句发送【数据库CPU使用率预警】邮件

单独的邮件扩展了原始收集CPU信息中的邮件部分。首先是汇总数据，显示取样区间、超过阈值的次数、最高CPU使用率、首末次超过时间。然后取首末次超过时间±5分钟范围内的CPU使用率明细数据

每10分钟获取最近10分钟的CPU使用率信息，仅保存sqlserver进程CPU使用率>0的记录。邮件每1小时从CPU使用率信息表筛选记录，邮件中的取样区间，由于sqlserver进程CPU使用率=0，显示时间区间可能不是完整的一小时。
