整体架构与ceilometer很类似

• Yagi consumes these notifications from the queue and passes them onto a chain of Yagi Handlers.
• Some yagi handlers include:
  • Shoebox for long-term archiving.
  • Atom-Hopper for pub-sub ATOM feeds.
  • Stack-distiller/Winchester for StackTach.v3 stream processing.
• Winchester takes the distilled notifications (called events) and stores them in the MySQL database.已经在ceilometer实现了
• Streams may be created or processed as new events flow into the system. This can result in new events or notifications being generated.
• Any new notifications can be published back into the queue for subsequent processing via theNotabene pipeline handler.
  目前ceilometer正在实现的功能。
• ... the sequence repeats itself.
