3. daemon­kit http://github.com/kennethkalmer/daemon-kit Kenneth Kalmer @kennethkalmer http://opensourcery.co.za
4. daemon­kit ?  Opionated Framework for Ruby daemons  Keep things DRY  Generators to help make things simple  Rake tasks to help keep things simple
5. Multiple environments  Development  Be noisy, break early, break hard  Testing  Staging  Production  Be quiet, stay alive, recover easily
6. Don't worry about pid files  Managed for you  Infered or explicit files  Great for controlling clusters  Handles stale pid files
7. Don't worry about logging  Multiple levels  Syslog support  Log rotation friendly (HUP)
8. Don't worry about configuration  Simple YAML config files  On­demand hashes  Environment­aware configuration  Defaults and environment specific overrides
9. Don't worry about monitoring  Generate monit/god configuration files via rake
10. Don't worry about silent death  Safety nets for threads  Hoptoad integration  Exception emails  Change logging levels with SIGUSR1/SIGUSER2
11. Generators accelarate  AMQP consumer  Nanite agent  XMPP bot  Cron daemon  Ruote remote participants   $ daemon_kit mydaemon ­i amqp
12. Easy deployment  Custom capistrano recipe tailored for daemons  Awaiting vlad contribution :)   $ daemon_kit mydaemon ­d capistrano  $ ./script/generate deploy_capistrano
13. Suitable for networking  EventMachine is a dependency  AMQP uses EM  Scheduler uses EM  XMPP to use EM (under construction)
14. Looking forward  RobustThread support  Bundled thread/fibre pool implementation  Sys V Init script generation  Bleakhouse support  Privilege dropping & chroot'ing
