Understanding Jmeter Results

Jmeter:Understanding Summary Report

The summary report shows values about the measurement Jmeter has done while calling the same page as if many users are calling the page. It gives the result in tabular format which you can save as .csv file.
These are some main headings in the summary result listener. Lets understand them in detail:

Summary Report












In the above image you can see in the red lined box: Label, Samples, Average, Max, Min, Std.Dev, Error%, Throughput, KB/Sec, Avg.Bytes.
  
LabelIn the label section you will able to see all the recorded http request, during test run or after test run.


SamplesSamples denote to the number of http request ran for given thread. Like we have one http request and we run it with 5 users, than the number of samples will be 5x1=5.
Same if the sample ran two times for the single user, than the number of samples for 5 users will be 5x2=10.


Average:  Average is the average response time for that particular http request. This response time is in millisecond. Like in the image you can see for first label, in which the number of sample is 4 because that sample run 2 time for single user and i ran the test with 2 user. So for 4 samples the average response time is 401 ms.


MinMin denotes to the minimum response time taken by the http request. Like for the above image the minimum response time for first four samples is 266 ms. It means one http request responded in 266 ms out of four samples.


MaxMax  denotes to the maximum response  time  taken by the http request. Like for the above image the maximum response time for first four samples is 552 ms. It means one http request responded in 552 ms out of four samples.


Std.Deviation:  This shows how many exceptional cases were found which were deviating from the average value of the receiving time.   The lesser this value more consistent the time pattern is assumed.


Error %: This denotes the error percentage in samples during run. This error can be of 404(file not found), or may be exception or any kind of error during test run will be shown in Error %. In the above image the error % is zero, because all the requests ran successfully.


Throughput The throughput is the number of requests per unit of time (seconds, minutes, hours) that are sent to your server during the test.
内容概要:本文档为《400_IB Specification Vol 2-Release-2.0-Final-2025-07-31.pdf》,主要描述了InfiniBand架构2.0版本的物理层规范。文档详细规定了链路初始化、配置与训练流程,包括但不限于传输序列(TS1、TS2、TS3)、链路去偏斜、波特率、前向纠错(FEC)支持、链路速度协商及扩展速度选项等。此外,还介绍了链路状态机的不同状态(如禁用、轮询、配置等),以及各状态下应遵循的规则和命令。针对不同数据速率(从SDR到XDR)的链路格式化规则也有详细说明,确保数据包格式和控制符号在多条物理通道上的一致性和正确性。文档还涵盖了链路性能监控和错误检测机制。 适用人群:适用于从事网络硬件设计、开发及维护的技术人员,尤其是那些需要深入了解InfiniBand物理层细节的专业人士。 使用场景及目标:① 设计和实现支持多种数据速率和编码方式的InfiniBand设备;② 开发链路初始化和训练算法,确保链路两端设备能够正确配置并优化通信质量;③ 实现链路性能监控和错误检测,提高系统的可靠性和稳定性。 其他说明:本文档属于InfiniBand贸易协会所有,为专有信息,仅供内部参考和技术交流使用。文档内容详尽,对于理解和实施InfiniBand接口具有重要指导意义。读者应结合相关背景资料进行学习,以确保正确理解和应用规范中的各项技术要求。
