/**
 * Transaction
 a).transaction适合记录跨越系统边界的程序访问行为，比如远程调用，数据库调用，也适合执行时间较长的业务逻辑监控
 b).某些运行期单元要花费一定时间完成工作, 内部需要其他处理逻辑协助, 我们定义为Transaction.
 c).Transaction可以嵌套(如http请求过程中嵌套了sql处理).
 d).大部分的Transaction可能会失败, 因此需要一个结果状态码.
 e).如果Transaction开始和结束之间没有其他消息产生, 那它就是Atomic Transaction(合并了起始标记).
 Event
 a). Event用来记录次数，表名单位时间内消息发生次数，比如记录系统异常，它和transaction相比缺少了时间的统计，开销比transaction要小
 
 type和name的组合要满足全局唯一性
    Transaction type有 "URL", "SQL", "Email", "Exec"等
    Event type有 "Info", "Warn", "Error"
 * @return
 * @throws Exception
