The agent extensions are managed and stored in the server. You can access the management view by clicking the Tools link in the side bar.
The Extensions tab presents a list of all available extensions, stored in the server. If an extension has an icon next to its class name, it means there is a source code of this extension, which you can see by clicking this icon.
In order to add new extensions click the New extension item in the Options menu. Then, select the jar file with the extension classes. If the jar file contains valid extensions, you should get a view with detected extensions.
You can verify that the extensions you upload are the ones you wanted before you send them to the server. When a new extension class is already present in the server registry, you will see a red icon in the Overwrite column. If the extension has its source code attached, you will see a green icon in the Source attached column. If everything is fine, just press the Accept button to upload the extensions.
