Jolokia is a fresh way of accessing JMX MBeans remotely. It is different from JSR-160 connectors, as it is an agent based approach that uses JSON over HTTP for its communication. It provides new features for JMX remoting: bulk requests allow for multiple JMX operations with a single remote server roundtrip, there is a fine-grained security mechanism for restricting JMX access on specific JMX operations, JSR-160 proxy mode, and history tracking, to name a few. Jolokia's origins are in jmx4perl. Client bindings in addition to Perl have already been added, and more are planned.
jmxtrans is effectively the missing connector between JMX and whatever logging or graphing package that you can dream up. jmxtrans is very powerful tool that reads JSON configuration files specifying servers/ports and JMX domains/attributes and then outputs the data in whatever format you want via special "Writer" objects that you can code up yourself. It does this with a very efficient engine design that will scale to querying literally thousands of machines. The core engine is pretty solid and writers are included for cacti/rrdtool, graphite, and stdout.
The Resilient Streaming Protocol (RSP) is a one-way IP/UDP media streaming protocol that was developed to provide high reliability audio streaming between the mountainchill.com Internet radio station's rural studios and SHOUTcast servers. Although the protocol operates in a unidirectional fashion (without listener ack/resend packets), it does support optional listener reporting and packet quality tracking. A streaming server called rspServer is included. It accepts multiple RSP stream sources, providing both RSP and SHOUTcast compatible relaying and transcoding. The source code package also includes a command-line encoder and decoders.
KnLiveCommentary is a realtime video comment streamer. It allows the task of adding comments and showing comments while playing a video stream in realtime. Video data and comments are fetched from a server and comments are displayed as scrolling top or bottom captions as the video advances. KnLiveCommentary also allows an authentication method and provides functions for filtering live comments. This is a project inspired by the video player at nicovideo.jp.
