AMF Dissector Plugin¶
The Action Message Format (AMF) Dissector provides a means to see the AMF messages being sent to and from the server from within FusionReactor’s Request Detail page. AMF is a binary format used to serialize ActionScript objects. It is used primarily to exchange data between an Adobe Flash application and a remote service, usually over the internet. The AMF tab can be found under the Request Details Page.
FusionReactor makes it easy by decoding your streaming AMF connections to help you debug your applications.
Figure 1: Decoded AMF details.
The AMF Dissector Plugin | Configuration (accessible from the Active Plugins page) allows you to alter the following:
|Dissector Mode||This allows you to record either Input AMF, Output AMF, Both or None. Decoded AMF data can be viewed by going on Request History and clicking the detail button ( ) and then clicking on the tab that is named "AMF" (as seen in Figure 1).|
|Buffer Size (bytes)||This is the buffer size you can allocate to each message. It is advisable that you select a reasonable size otherwise data may get rejected by the dissector.|
|Number of Messages||This is the number of messages in an AMF stream that can be stored per transaction.|
|Streaming Message Store Mode||Store First Messages - When the buffer is full the most recent messages will be discarded.
Store Latest Messages - When the buffer is full the older messages will be discarded.
|Message Display Ordering||This allows you too choose the order that messages are displayed, choosing Newest First means that the most recent messages are displayed first. Choosing Oldest First means that the oldest messages will be displayed first.|
No log files about captured data are generated from this plugin.
