Introduction

INTRODUCTION

Introduction

Why do we use JMeter?

Considering a typical web-application, we could have 1000s of userstrying to access it concurrently. We may not choose to employee1000 testers for every such user for performance evaluation of theapplication.

Introduction

Bandwidth Throttling

Bandwidth throttling is the intentional slowing of Internetservice.

In real world scenario, people use different web services atdifferent bandwidths.

Using Bandwidth Throttling, JMeter can be used to create testplans to simulate slower connections.

Bandwidth Throttling User Interface

User Interface

To use bandwidth throttling in JMeter, a gui component hasbeen added to HTTP Request Defaults Config Element.

Dynamic Bandwidth Throttling

1 DBT deals with the variation of bandwidth at runtime.

2 DBT can be used to test performance of web services undervarying bandwidth (load).

3 DBT can be used to measure and manage errors during the testat runtime.

4 Based on error rate.

5 A distributed testing can be simulated using DBT and IPspoofing.

IP Spoofing

IP Spoofing What is IP address Spoofing?

What is IP address Spoofing?

It is the creation of IP Packets with forged source IP address, withthe purpose of concealing identity of the sender or for impersonatinganother computer system.

IP Spoofing IP Spoofing in JMeter

IP Spoofing in JMeter

1 JMeter is capable of generating thousands of threads that act asvirtual users

2 On the server side, these requests appear from the same IPaddress on which JMeter resides

3 On servers which have IP dependent response, the testplan witha thousand virtual fails

4 To eliminate this drawback, we use IP Spoofing in JMeter

IP Spoofing JMeter Implementation

JMeter Implementation

IP and Subnet Details

We need to provide JMeter with IP address of the machine and thesubnet it belongs to, and also specify the number of IP addressesrequired

IP allocation

JMeter internally allocates virtual IPs to the same machine, and eachvirtual user can send request from a distinct IP from newly allocatedvirtual IPs

Automating TPC-C Benchmarking

TPC- Transaction Processing Council It defines transactionprocessing and database benchmarks and delivers trusted results.

Some benchmarks undertaken under TPC:

TPC-APPTPC-HTPC-C

Automating TPC-C Benchmarking WHY TPC-C?

WHY TPC-C?

A number of these benchmarks have been deprecated. TPC-C iscurrently in use and a rather complex process.

A number of business houses use this benchmark to showcasetheir performance for OLTP transactions. It gives the measureof Server speed for online transaction processing.

The actual benchmarking process is a time taking and a costlyaffair.

A preliminary test would be a highly useful tool to test a serverfor performance and hence improve it where it lacks.

Why JMeter to automate??

JMeter is already capable of spawning a large number of virtualusers to simulate the interaction of the real users with thesystem under test.

The firing of a request and measurement of response time aswell as throughput is embedded in JMeter.

Challenges

1 Auto CSV Generation:Generating CSV file for a particular table from a specifiedDatabase

2 Dynamic Bandwidth Throttling:Changing bandwidth in runtime and determining a reliableparameter (Percentage Error) to implement throttle bandwidth

3 IP Spoofing:Finding an array of un-used IPs and automating allocation ofvirtual IPs for a system

4 Automating TPC-C testing:Making tpcc testing capable of being run with differentdatabases incroporating all the standards into JMeter

Challenges

Future Work

1 Incorporating other Benchmarking support such as TPC-H,TPC-E etc. into JMeter.

2 Automation of the test scripts, as in user may not have to createthe test script, and Jmeter can itself do it for the tester bytechniques such as web crawling, etc.

3 The instability of JMeter on large loads could be worked outwith some solution.

4 Bringing large download efficiency into JMeter.

5 Better analysis of the results produced by JMeter via somecomplex graphs and better comparison between different graphresults.

Future Work

Conclusion

The basic aim of the project was to enhance JMeter with theintroduction of some new features and overcome somedrawbacks.

We have made JMeter capable of performing more practical testswith the introduction of bandwitdh throttling and IP Spoofing.

The user friendliness of JMeter has been improved with theintroduction of auto csv generation and results filtering.

Finally Jmeter has been extended from just a load testing tool toa Preliminary TPC-C benchmarking tool.
