100% Availability is something even big banks do not guarantee.
This is live example i faced today.

Activity Pause

2011-05-12T12:12:00.000-07:00

hi..
i am pausing this activity of daily collecting performance news and updating in this blog due to
1. Lack of readership.
2. Lack of time.
Pis a vertical and it is not possible to get into the depth and breadth at the same time. Performance in itself does not exist. It has to take the support of something else, like application or infrastructure.
Thanks.
If you wish to contact me, please feel free to at avirads at gmail dot com.

It is important to understand the intention of the person who is projecting performance test results.

Data is neutral. But the way it is projected can be flawed.

Just like they say in statistics "lies, damn lies and statistics",

After completion of the performance test, all that we have is data.

Sometimes, data may be hidden and not shown in the results.

Sometimes, the comparison metric used may be flawed.

Sometimes, when an enhanced version of an existing product is released, often stated change is performance improvement.

Writing JMeter tests using JavaRequest

2009-09-14T21:02:00.001-07:00

JMeter supports performance testing of services that have clients written in Java using Java Request. Here are the steps needed to write a simple performance test client with that support.

1. import the necessary classes

import org.apache.jmeter.* ...

2. Create a class that implements JavaSamplerClient. Ex: JavaTester

3. Override the life cycle methods setupTest, teardownTest, runTest, getDefaultParameters

4. In the method runTest create an object of the typw SampleResult and flag the test as successful or failed based upon the response from the server.

5. Place the files ApacheJMeter_core.jar and ApacheJMeter_java.jar in classpath and compile the class JavaTester and make a jar out of it. jar -cvf JavaTester.jar JavaTester*

6.Place any additional jar files required in lib/ext directory

7. Restart JMeter, create a thread group and add a Sampler of the type Java Request. Observe that the Classname combo box should display the compiled java file, JavaTeser.

You are good to go. This is how the class looks like

import org.apache.jmeter.protocol.java.sampler.*;
import org.apache.jmeter.config.Arguments;
import org.apache.jmeter.samplers.SampleResult;

public class JavaTester implements JavaSamplerClient {

public void setupTest(JavaSamplerContext context) {
}
public void teardownTest(JavaSamplerContext context) {
}
public SampleResult runTest(JavaSamplerContext context0) {
    SampleResult results = new SampleResult();
    try{

        //put code here that sends the request to the server

         results.setSuccessful(true);
     }catch(Exception exc){
         results.setSuccessful(false);
     }
     return results;
}
public Arguments getDefaultParameters() {
    Arguments params = new Arguments();
    return params;
}

}

Index Engines, http://www.indexengines.com/, is touting “Unmatched Speed. Unprecedented Scale.” for its 3.0 platform. The platform function discovers full content and metadata of LAN data, classifies it, indexes it (up to a billion files and e-mail!), and sets up a streamlined, “blazing fast” search: one terabyte per hour using a single indexing node.

This Book presents the range of analytical tools and techniques that ensure traffic performance and quality of service in telecommunication systems and networks.
