Transcript

  • 1. Rails exception tracking with Graylog2 Manage your logs in the dark and have lasers going and make it look like you're from space Lennart Koopmann RubyAndRails EU Amsterdam, 2010
  • 2. About me Lennart Koopmann 22 years old Living in Hamburg, working at Jimdo lennartkoopmann.net / @_lennart
  • 3. Log server with web interface.
  • 4. phpLogCon … let's not talk about that Graylog1: August 2009 Graylog2: August 2010
  • 5.  
  • 6. Syslog daemon (TCP/UDP)
  • 7. GELF (UDP)
  • 8. Graylog extended log format UDP - Max (GZIP) 8192 byte per message (Chunking is supported) Libraries for Ruby and PHP available
  • 9. { }
  • 10. { ' message ':'Exception: Something went wrong.' }
  • 11. { ' message ':'Exception: Something went wrong.', ' full_message ':'Stacktrace. Some env vars' }
  • 12. { ' message ':'Exception: Something went wrong.', ' full_message ':'Stacktrace. Some env vars', ' host ':'www19' }
  • 13. { ' message ':'Exception: Something went wrong.', ' full_message ':'Stacktrace. Some env vars', ' host ':'www19', ' file ':'/var/www/index.php' }
  • 14. { ' message ':'Exception: Something went wrong.', ' full_message ':'Stacktrace. Some env vars', ' host ':'www19', ' file ':'/var/www/index.php', ' line ':2638 }
  • 15. { ' message ':'Exception: Something went wrong.', ' full_message ':'Stacktrace. Some env vars', ' host ':'www19', ' file ':'/var/www/index.php', ' line ':2638, ' level ':1 }
  • 16. { ' message ':'Exception: Something went wrong.', ' full_message ':'Stacktrace. Some env vars', ' host ':'www19', ' file ':'/var/www/index.php', ' line ':2638, ' level ':1, ' something ':'foo' }
  • 17. { ' message ':'Exception: Something went wrong.', ' full_message ':'Stacktrace. Some env vars', ' host ':'www19', ' file ':'/var/www/index.php', ' line ':2638, ' level ':1, ' something ':'foo', ' something_else ':'bar' }
  • 18. Chunking
  • 19. Use Cases
  • 20. Plain syslog Collect everything of your /var/log from all servers, aggregate, analyze and get a warning if something goes wrong
  • 21. GELF Embed it into the logging class of your application and trigger with every error. Include stacktrace and env vars in full message. Later filter by file:line to get statistics.
  • 22. Aggregate, analyze and get a warning if something goes wrong
  • 23. Notifications Currently only Nagios hook (rake task) – Triggered at too many messages in last X minutes
  • 24. Average page generation time Graylog1 / MySQL: ~12000ms
  • 25. Average page generation time Graylog1 / MySQL: ~12000ms Graylog2 / MongoDB: ~250ms
  • 26. Exception tracking with Rails Rack middleware available as gem
  • 27. lennart ~$ sudo gem install graylog2_exceptions Successfully installed gelf-0.9.1 Successfully installed graylog2_exceptions-0.5.3
  • 28. # config/environment.rb config.middleware.use " Graylog2Exceptions ", { :host => ' 127.0.0.1 ', :port => ' 12201 ', :local_app_name => ' mama ' }
  • 29. Roadmap
  • 30. Incident management Define chained rules that explain an incident. Trigger several actions when incident occurs.
  • 31. Fine grained notifications Be informed via Email, XMPP, SMS by Graylog2 directly without Nagios hook
  • 32. More analyzing
  • 33. More search features
  • 34. Live demo. www.graylog2.org / @Graylog2 www.lennartkoopmann.net / @_lennart (Slides are on Slideshare)
