How to use JMeter
Introduction
JMeter can be used to simulate a heavy load on a server, group of servers, network or object to test its strength or to analyze overall performance under different load types. We can use it to make a graphical analysis of performance or to test server/script/object behavior under heavy concurrent load.
What can we do with JMeter?
Ability to load and performance/stress test many different server/protocol types:
- Web — HTTP, HTTPS (Java, NodeJS, PHP, ASP.NET, …)
- SOAP / REST Webservices
- FTP
- Database via JDBC
- LDAP
- Message-oriented middleware (MOM) via JMS
- Mail — SMTP(S), POP3(S) and IMAP(S)
- Native commands or shell scripts
- TCP
- Java Objects

Set java heap size
We should modify some lines from the line #44 in file “jmeter” to optimize for you.
Run JMeter
Load/save a model
click “file — open/save” on the menu bar
Start to test
click “run — start” on the menu bar
Make a example model
Test plan is a model that we want to test like.
1. Right click on “Test plan” and than select Add — Threads (Users) — Thread Group
2. Right click on “Thread Group” and than select Add — Config Element- HTTP Request Defaults 3. Right click on “Thread Group” and than select Add — Logical Controller — Loop Controller
4. Right click on “Loop Controller” and than select Add — Sampler — HTTP Request
Record own browser requests via proxy
We can record own browser requests via proxy
1. Right click on “Test plan” and than select Add — Threads (Users) — Thread Group
2. Right click on “Thread Group” and than select Add — Logical Controller — Recording Controller
3. Right click on “WorkBench” and than select Add — Non-Test Elements — HTTP(S) Test Script Recorder
4. Set configuration of Target Controller in HTTP(S) Test Script Recorder to “Test Plan > Thread Group > Recording Controller” 5. Set proxy on OS configuration.
6. Click “start” button in HTTP(S) Test Script Recorder.
7. Open own browser and than surfer a website as you want to
