It is binary and looks like this:. Now, we can create more than one thread. But then we lose the possibility of parameterizing the requests, and we cannot read the answers again. This way we can deserialize the response and display it in String format. The functionality of this plug-in is similar: Besides, in some cases, there may be a situation, which we have in the second example, when the message contains the clientId, which is allocated strictly to one connected SWF file and is saved in the binary file.

As a result, it will be possible to run only one thread, which is absolutely not suitable for load testing.
This in-depth tutorial will show you how JMeter can load test applications that am the AMF protocol, as well as serializing and deserializing messages. But, we will not be able to read the answer. After creating your script in JMeter, you can analyze the results in real-time on BlazeMeteror after a few months to see changes in your performance. You can choose one of these: To try out BlazeMeter, request a demoor put your URL jmetet the box below and your test will start in minutes.
DZone ‘s Guide to. Join the DZone community and get the full member experience. Charles – ajf debugging proxy that supports the AMF messages format, but is commercial has a demo period.
This means that the data is presented as an XML message that contains the name of the procedure that will be executed on the server, and its parameters. Charles displays this data in the following plguin It is binary and looks like this: After that, we can do whatever we want with the answer. But here, too, there is a small drawback: The second example is a Flash application that uses the AMF format for communication between the client and the server.
If you get the following error when you decode the message using the code above or the JMeter AMF Plugin, it means that your server is sending you a type of data that you do not know anything about and you need to write your own serialization scheme.
Because Flex uses the AMF protocolthe steps covered here will show how to test this protocol with JMeter and can be implemented for any app that uses it. In this blog post we will present 2 examples: To work with it, you need to put blazeds-common.
Over a million developers have joined DZone.
You can choose one of these:. Next, before sending, this data is serialized and we get a binary AMF message that is sent to plugib server, where it will be deserialized and the corresponding procedure will be called.
Here you can download the JMeter script with both examples.
Flex uses two variations of the AMF protocol. In this example, we will demonstrate plugon testing the sending and serialization of messages. This way we can deserialize the response and display it in String format.
JMeterPlugins – Apache JMeter – Apache Software Foundation
See the original article here. For this, we can use proxy applications that support the AMF format. There may be two situations: Besides, in some cases, there may be a situation, which we have in the second example, when the message contains the clientId, which jmeher allocated strictly to one connected SWF file and is saved in the binary file.
BurpSuite is a proxy application too, but with a free version.
Therefore we need the ability to read and change AMF messages. Opinions expressed by DZone contributors are their own. In our example, it is information about jmeteer maybe something elseand we can not deserialize it because we know nothing about the server implementation. In kmeter article, we will discuss how to load test applications that are based on the Flex Frameworkwith Apache JMeter. The functionality of this plug-in is similar: Monitor KPIs like response time, error rate and hits in interactive graphs that are simple to use and easy to understand, and share results with team members, managers and non-technical audiences.
