Run from console

jmeter -n -t testplan.jmx -l listener.jtl

Few things to remember

• Generate log file using –l option, good for generating other test

results later

• Use jmeter plugins console status logger

• Gives current status of tests

• jMeter plugins graph listeners

Run in distributed mode

Why to run in distributed mode

What are the indicators to go for distributed mode

Few things to take care of

• Same java version

• Same jMeter version

• Keep the time on all

machine synchronized

• Node specific data needs to managed

appropriately in test plan

• Higher duration for reporting results

Extra set of jMeter plugins

Needs jMeter 2.8 and JRE 1.6 or above

We will discuss

• Few from Standard set

• Few from Extra set

Dummy sampler

Test writer can set • What is request data

• What is response code

• What is response message

• What is response time

• What is response data

Very useful for programming tests

Very useful for debugging tests

And more importantly learning jMeter

13 www.kpoint.com

Graph listeners

Graph listeners

• Hits per second

• Transactions per second

• Response time distribution

• Response time percentile

• Response time vs threads

Do try out ultimate group controller with dummy sampler

and various graph listener to

kPoint kapsule streaming test

What is the test

What is involved in kapsule view test

• Progressive video download

• Slide and application share data on the given timeline

• View progress updates

The purpose is to show you glimpse how comprehensive

test can be implemented using jMeter

Let’s look at the test

Tools comparison

jMeter/Grinder/Tsung

What's similar

• Open source

• Good community support

• Script recording support

• Support for http/https

• Support non-http protocols

What's different

• Programming interface

• jMeter -> UI based programming constructs (Underneath its XML)

• Grinder -> Jython

• Tsung -> XML

17 www.kpoint.com

Tools comparison Support for generating huge load

• jMeter -> supports distribute mode execution and result collection

• Grinder -> Very good support for running in cluster

• Tsung -> Apparently best of all 3

What's good for me, well depends

• Ease of usage

• jMeter has gui so easy to get started

• Grinder does require knowledge of python and leaves lots to the test writer

• Tsung is XML

• Application/Protocol to be tested

• jMeter has support for huge number of protocols

• Grinder do not support out of the box, but all kind of java/python libraries can be used to create different protocol tests

• Tsung has good enough set of protocol support

• Stress to be generated

• All are comparably capable
