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,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);
