[Andres Rodriguez]

Blueprint changed by Andres Rodriguez:

Whiteboard changed:
  Work Items:
  [andreserl] Dynamically reload configuration: DONE
- [andreserl] Support for MODULES and SERVICES: INPROGRESS
+ [andreserl] Support for MODULES and SERVICES: DONE
  Move monitors to asynchronous mode (ProcessMonitor with netlink): TODO
  Support for PowerSave profiles: TODO
  GTK for selection of PowerSave profiles: TODO
  Finish Client/Server approach: TODO
  OpenStack Power Scheduler integration: TODO
  Messaging with RabbitMQ: TODO
  Integration with NUT: TODO
  
  = Agenda ==
  
   * Feature request/review
   * Client/Server approach to deploy PowerNap datacenter wide.
     * Server ARP monitoring for automatic wakeup.
   * Integration with NUT
   * Server Pivot mode for Orchestra
   * Desktop/Server profiles
   * Integration with other projects, such as OpenStack, Landscape etc.
   * White/Black lists of known good/bad hardware
  
  Previous work items:
  
  [andreserl] Add auto-publishing support for PowerNap clients via avahi: POSTPONED
  [andreserl] Add component listener to Powerwaked for auto-registration (Server): POSTPONED
  [andreserl] Provide powerwaked to check status of registered machines in a Client/Server fashion: POSTPONED
  [andreserl] Provide powernapd with a method to listen messages from powerwaked: POSTPONED
  [andreserl] Change polling monitoring system to event based system: POSTPONED
  [andreserl] Look into integration of PowerNap/PowerWaked with NUT: POSTPONED
  [andreserl] Investigate/add additional pm-powersave tweaks from ARM: POSTPONED
  [andreserl] Define sample profiles i.e. For Web Servers, File Servers, Laptops etc: POSTPONED
  [andreserl] Perhaps involve someone on the Desktop Team to improve powernap for Laptops: POSTPONED
  [andreserl] Add pre-start to upstart job to determine whether machine is virtual or physical (facter virtual): POSTPONED
  
  == Agenda ==
  
   * Client/Server approach to deploy PowerNap datacenter wide.
     * Server ARP monitoring for automatic wakeup.
     * Server Pivot mode for Orchestra
     * OpenStack + Orchestra testing/integration
       * might be implemented differently than UEC/Eucalyptus/PowerNap, but we need something similar at least
   * Integration with NUT
    * powerwake mode to talk to nut to power systems on
    * powernap "remote" mode to talk to nut to power remote systems down
   * Desktop/Server profiles
    * currently have one set of profiles used by all systems
    *
   * New tricks to reduce power consumption
   * White/Black lists of known good/bad hardware
   * Feature request/review
  
  == Outcome ==
  
  OpenStack Power Scheduler Integration.
   * RabbitMQ?
       * Some random people seem to consider moving away from rabbitMQ for another AMQP implementation (to be confirmed with actual working code)
       http://osdir.com/ml/openstack-cloud-computing/2011-10/msg00522.html
  
  Gnome power (or UPower?) daemon integration/interaction
   * add a configuration option to enable GPD to use the powernap state to determine machine's activity or non-activity
   * test modern 3.2 kernel (against 2.6.38), verify kernel doing the right thing on idle CPUs, and hopefully purge PowerNap's cpu offline script
   * upstart/dbus/inotify integration as asynchronous monitoring systems
     * Move one monitor to asynchronous mode (prove it can be done, show how to do it)
       * ProcessMonitor - netlink for process creation/deletion
