The Anubis distributed state monitoring components were added to the SmartFrog open source today.
Anubis is a fully distributed state monitoring service that provides discovery, status monitoring and failure detection capabilities. Anubis implements timely and consistent reporting of distributed state information and includes awareness of network partitions. Using Anubis, SmartFrog components can announce their existence and current state, discover and observe other components, and determine the absence or failure of other components.
Anubis will be packaged for download in future releases, but is currently available in the CVS repository under:
