loadrunner之用户自定义数据采集
Loadrunner中lr_user_data_point、lr_user_data_point_instance两个函数可以用来记录一条自定义的Vuser运行数据，并将其输出到测试结果中，最后可以通过分析工具Analysis来分析数据采集情况。两者之间的区别是lr_user_data_point_instance函数可以用来记录指定事物实例的自定义数据。
函数语法：
int lr_user_data_point (const char *sample_name, double value);
long lr_user_data_point_instance (const char *sample_name, double value, long transaction_handle);

上面两脚本在Controller中执行完成后，就可以在Analysis中查看运行结果。启动分析工具后，点击Graph>>Add New Graph或者ctrl+a快捷键来打开新采集到得图表，可以看到User Ddfined Data Points下面有Ddfined Data(Sum)和Ddfined Data(Average)两类图表。双击对应的图表就会将用户自定义的数据分析结果添加到网页细分图里面。
依次点击菜单Report>>Crystal Report>>Performance Report>>Data Point,就可以查看到各个Vuser运行时，用户自定义数据采集出来的具体信息了，如下图所示。对于自定义的一些相关业务交易信息之类的，在性能分析方面可以比较深入的分析出程序的瓶颈。
