添加事物
Action() { lr_start_transaction("openindex"); web_url("WebTours", "URL=http://127.0.0.1:1080/WebTours/", "Resource=0", "RecContentType=text/html", "Referer=", "Snapshot=t3.inf", "Mode=HTTP", LAST); lr_end_transaction("openindex", LR_AUTO); return 0; }
运行结果：
Action.c(4): 通知: Transaction "openindex" started. Action.c(6): web_url("WebTours") 已成功，312 个正文字节，164 个标头字节 [MsgId: MMSG-26386] Action.c(15): 通知: Transaction "openindex" ended with "Pass" status (Duration: 0.4420 Wasted Time: 0.3987).
lr_end_transaction的4中状态
LR_PASS LR_FAIL 自定义事物成功和失败。也可以用 lr_set_transaction_status_by_name(LR_FAIL,"openindex"); 函数自定义事物状态
Action() { int status ; lr_start_transaction("openindex"); //web_url 成功返回0 失败返回1 status =web_url("WebTours", "URL=http://127.0.0.1:1080/WebTours1/", //不存在的网址 "Resource=0", "RecContentType=text/html", "Referer=", "Snapshot=t3.inf", "Mode=HTTP", LAST); if (status==0) { lr_end_transaction("openindex", LR_PASS); }else{ lr_end_transaction("openindex", LR_FAIL); } return 0; }
运行结果：
网址不存在 Action.c(6): 通知: Transaction "openindex" ended with "Fail" status (Duration: 0.4105 Wasted Time: 0.3801). 如果网址存在，请求成功： Action.c(15): 通知: Transaction "openindex" ended with "Pass" status (Duration: 0.3951 Wasted Time: 0.3687).
LR_AUTO
Action() { lr_start_transaction("openindex"); web_url("WebTours", "URL=http://127.0.0.1:1080/WebTours/1", //不存在的网址 "Resource=0", "RecContentType=text/html", "Referer=", "Snapshot=t3.inf", "Mode=HTTP", LAST); lr_end_transaction("openindex", LR_AUTO); return 0; } 运行结果： Action.c(4): 通知: Transaction "openindex" ended with "Fail" status (Duration: 0.4072 Wasted Time: 0.3774).
Action() { lr_start_transaction("openindex"); web_url("WebTours", "URL=http://127.0.0.1:1080/WebTours/", //网址正确 "Resource=0", "RecContentType=text/html", "Referer=", "Snapshot=t3.inf", "Mode=HTTP", LAST); lr_set_transaction_status_by_name(LR_FAIL,"openindex"); //手动设置事务失败 lr_end_transaction("openindex", LR_AUTO); return 0; } 结果： Action.c(14): 通知: Transaction "openindex" ended with "Fail" status (Duration: 0.4284 Wasted Time: 0.3811).
LR_STOP
事物返回时间的详细解释
Action.c(14): 通知: Transaction "openindex" ended with "Fail" status (Duration: 0.4284 Wasted Time: 0.3811).
Duration（持续时间）：事物开始一共的时间。包括Wasted Time、代码浪费时间。在Analysis获取的是 Duration-Wasted Time时间。
Wasted Time（浪费的时间）：LR为了支撑，工具内部的时间。事物的统计。用lr_start_timer() lr_end_timer()函数获取。
Action() { lr_start_transaction("openindex"); web_url("WebTours", "URL=http://127.0.0.1:1080/WebTours/", //网址正确 "Resource=0", "RecContentType=text/html", "Referer=", "Snapshot=t3.inf", "Mode=HTTP", LAST); //lr_think_time(3); lr_output_message("Duration:%lf;Wasted Time=%lf",lr_get_transaction_duration("openindex"),lr_get_transaction_wasted_time("openindex")); lr_end_transaction("openindex", LR_AUTO); return 0; } 运行结果： Action.c(13): Duration:0.389529;Wasted Time=0.361978
去掉lr_think_time注释
Action.c(13): Duration:3.384649;Wasted Time=0.352630 //Duration多了3秒
Action.c(14): 通知: Transaction "openindex" ended with "Pass" status (Duration: 3.3882 Think Time: 2.9994 Wasted Time: 0.3526).
程序消耗时间：
Action() { merc_timer_handle_t timer; char save[1000]; double wasteTime; int i; lr_start_transaction("openindex"); web_url("WebTours", "URL=http://127.0.0.1:1080/WebTours/", "Resource=0", "RecContentType=text/html", "Referer=", "Snapshot=t3.inf", "Mode=HTTP", LAST); timer=lr_start_timer(); for(i=0;i<1000;i++){ sprintf(save,"this is the way we wasteTime in a script %d",i); } wasteTime=lr_end_timer(timer);
//lr_wasted_time(wasteTime*1000); //把浪费的时间加到WastedTime.因为wasteTime是秒。lr_wasted_time接收的是毫秒。所以好*1000 lr_output_message("Duration:%lf;Wasted Time=%lf",lr_get_transaction_duration("openindex"),lr_get_transaction_wasted_time("openindex")); lr_end_transaction("openindex", LR_AUTO); return 0; } 运行结果： Action.c(22): 通知: Transaction "openindex" ended with "Pass" status (Duration: 3.0407 Wasted Time: 0.3701). 持续时间包括了程序时间。
去掉 lr_wasted_time注释。运行结果
Action.c(23): 通知: Transaction "openindex" ended with "Pass" status (Duration: 3.7046 Wasted Time: 3.6650).
可以看到for循环运行的时间，被加到了Wasted Time
需要注意的
1）事务中不要插入日志函数
2）不要插入集合点函数
3）尽量不要插入思考时间
