lr_start_sub_transaction	标记子事务的开始
lr_start_transaction	标记事务的开始
lr_end_sub_transaction	标记子事务的结束以便进行性能分析
lr_end_transaction	标记 LoadRunner 事务的结束

    思考时间大于阈值时生成： 使用思考时间的阈值。如果录制思考时间小于该阈值，VuGen 将不会生成思考时间语句。您也可以指定阈值。默认值为 3 - 如果思考时间少于 3 秒，VuGen 将不会生成思考时间语句。如果禁用此选项，VuGen 将不会生成任何思考时间。（默认情况下启用）

脚本：

    lr_start_sub_transaction("think time1","t1");

    lr_think_time(10);

    lr_end_sub_transaction("think time1",LR_PASS);

    lr_start_sub_transaction("think time2","t1");

    lr_think_time(10);

    lr_end_sub_transaction("think time2",LR_PASS);

       lr_end_transaction("t1", LR_AUTO);

 

输出：

 

Action.c(8): Notify: Transaction "t1" started.

Action.c(9): Notify: Transaction "think time1" started.

Action.c(10): lr_think_time: 10.00 seconds.

Action.c(11): Notify: Transaction "think time1" ended with "Pass" status (Duration: 9.9939 Think Time: 9.9892).

Action.c(12): Notify: Transaction "think time2" started.

Action.c(13): lr_think_time: 10.00 seconds.

Action.c(14): Notify: Transaction "think time2" ended with "Pass" status (Duration: 9.9954 Think Time: 9.9906).

Action.c(15): Notify: Transaction "t1" ended with "Pass" status (Duration: 19.9994 Think Time: 19.9798).
