RE: Hi All, What to do in the beginning
How you all doing? I have pinpointed my requirements for now with Jmeter. I gotto test Java applications(lets for now say its not an web app). For example suppose a Java app is having n number of objects. How, by using Jmeter I can understand which object is creating the bottleneck in the entire app? If somebody is giving me a testscript, pls. briefly explain how to connect that with Jmeter and run. As I told earlier I am not very good in J2EE technologies.I dont know XML. I will learn the relevant parts for testing Jmeter. Thanks and looking forward to hear.

RE: Hi All, What to do in the beginning
Hi souyma As far as i'm aware JMeter won't do this sort of thing for you. JMeter is capable of showing how your application will scale under load but it will give you little indication as to where bottelnecks that prevent scaling occur. You should look into using a profiling tool such as OptimizeIt or JProbe (possibly in conjunction with JMeter to load the system whilst testing).

I have used JMeter to load a system while running JProbe to find where bottlenecks were. JMeter is perfect for that purpose. However, JMeter currently only supports http, JDBC, and FTP (and somewhere I have SMTP classes lying around that I haven't merged yet). However, if you can write java, it's not so hard to add your own classes to do new stuff. You would have to write, at a minimum, a sampler (which does the actual calling of your java objects), a controller (which would hold configuration information and create Entry's to be "executed" by your sampler), and a GUI for your controller. Most likely, you'd also have to create some ConfigElement classes for greater flexibility. It's not as hard as it sounds once you understand what a SamplerController does, and what a Sampler does. Is this something you want to tackle? If so, I'm willing to help. -Mike > > Stu > > > -Original Message- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] > Sent: Friday, June 15, 2001 2:32 PM > To: [EMAIL PROTECTED] > Subject: RE: Hi All, What to do in the beginning > > > How you all doing?

RE: Hi All, What to do in the beginning
Thanks Mike & Stuart for your replies. So its pretty clear that for the purpose of finding the bottle neck in an application we need to load the app by Jmeter and use the Profiling tool for finding the bottleneck. So I will start loading a Java app with Jmeter. Yes, I can write Java classes. So, let me know where and what do I have to do to understand how to write a sampler and samplercontroller. How does Jmeter help me in doing so? Can I subclass these from Jmeter and start writing my code? Please give me a brief outline and I will start with this. in fact Mike has already done this JProbe+Jmeter thing. So I will need to follow the steps. I couldnt get the JProbe licence. I got the OptimizeIt licence though. So I will be usimg Jmeter+OptimizeIt.
