- 10. Patterns: Monitoring! Monitoring as a service:! • Check in your checks and monitoring is free! • Transparency => shame => compliance! Ongoing challenges:! • Pager fatigue! • Automate all the thresholds ! • Dependencies => deduplicating alerts! • Drive => Host => Service => Application => User! 10! ! 7/21/14! © 2014 StackStorm, Inc.!

- 12. Patterns: Monitoring! Infer the threshold! • Anomaly detection! • Pattern recognition! Start with a check! And/or update the checks and thresholds as you learn more! Monitoring as a service " Remediation as a service! 12! ! 7/21/14! © 2014 StackStorm, Inc.! Confidential!
- 13. Remediation as a Service #1! 13! ! Facebook’s FBAR: “AutomaRng the work of hundreds” h4ps://www.facebook.com/notes/facebook-‐engineering/making-‐facebook-‐self-‐ healing/10150275248698920 7/21/14! © 2014 StackStorm, Inc.! Confidential!
- 14. Remediation as a Service #2! 14! ! Microsoh AutoPilot: States: • Healthy, Failed, ProbaRon RemediaRons (“Rs”): • Restart, Reboot, Reimage, RMA h4p://research.microsoh.com/pubs/64604/osr2007.pdf “Machine learning algorithms to analyze these data in order to understand how to improve the policy selngs, with the ulRmate goal of automaRng many of the current manual policies. “
- 15. Patterns: Tools – Monitoring?! The #1 tool we have seen is NewRelic! • Roughly 75% of the discussions! • Amazing because it does not fit all the requirements! The #2 tool we have seen is Splunk! • Still seeing them more than LogStash, ElasticSearch although it is close! ! 15! ! 7/21/14! © 2014 StackStorm, Inc.! Confidential!
- 16. Patterns: Tools – Configuration! Puppet vs. Chef! • Ops vs. developers?! Ansible and Salt growing in importance! • Points of differentiation and also overlap! Best practices include:! • Separate source of truth ! • Code reviews (duh?)! 16! ! 7/21/14! © 2014 StackStorm, Inc.! Confidential!
- 17. “State in the Repo” vs. Single Source of Truth! 17! ! • Provides visibility into the system! • Fights configuration drift! • Reduces convergence time of changes! • Tied in to monitoring and configuration systems! 7/21/14! © 2014 StackStorm, Inc.! Confidential!
- 18. 18! ! Lack of trust Hard to test Simple script + simple script + simple script + Zounds What’s Wrong with Day 2 AutomaCon? Monitoring My script vs. your script IntegraCon sprawl
- 19. Automation: Don’t Forget #1! Simplicity scales. 19! ! Best. 7/21/14! © 2014 StackStorm, Inc.! Confidential! BEST PRACTICES • Have X states (three seems logical) for a monitored system • Have Y remediaRons • Document both • Automate the known mappings • Atomic acRons • Workflows or acRons of acRons to Re them together Lessons learned from many operators large and small
- 20. Automation: Don’t Forget #2:! Failure detectors must be able to dis7nguish between the symptoms of failure and overloading, otherwise overloaded computers may be marked as failed and removed from service, amplifying the problem and triggering a cascade of failures that disables the enRre applicaRon. 20! ! h4p://research.microsoh.com/pubs/64604/osr2007.pdf BEST PRACTICE Check a threshold with each step so that run away automaRons cannot occur. 7/21/14! © 2014 StackStorm, Inc.! Confidential!
- 21. Automation: Don’t Forget #3! Humans are good at pa4ern matching – if they perceive the pa4erns. • Always provide context. When a threshold is violated that requires that humans get back involved you are at risk of pulng the human in a difficult place. 21! ! BEST PRACTICE When the system needs a human, provide the human with context. • Automate the delivery of that context for the sake of consistency • Don’t allow the automa,on to just be addi,onal complexity on top of complexity 7/21/14! © 2014 StackStorm, Inc.! Confidential!
- 22. Automation: Don’t Forget #4! AutomaRon frees up humans to a4ack technical debt, refactor for growth and so forth. However, the implicit knowledge formed by eliminated manual acRon itself may be lost. 22! ! BEST PRACTICE Refer to the prior Don’t forget points including simplicity of state analysis and simplicity of allowed remediaRons. • Also – allow manual invoking of automaRons • Make automaRons human readable • And otherwise transparent • Give the automaRon an edgy personality (huh?) 7/21/14! © 2014 StackStorm, Inc.! Confidential!
- 23. ChatOps is Brilliant! Add some code to IRC or other chat to do stuff, and you have bot executed code. Add to that an enRre automaRon library – plus a personality – and the requirement that ALL changes happen through chat and DevOps happens. 23! ! BEST PRACTICES Get to know Hubot. And stay tuned for StackStorm’s take on this approach. ChatOps benefits: • Dev/Ops interface and Newby / Old pro interface • Context for humans • Trust in automaRon h4p://puppetlabs.com/blog/really-‐building-‐data-‐driven-‐infrastructure 7/21/14! © 2014 StackStorm, Inc.!

- 27. StackStorm! 27! ! Events AcCons #ShareAndLearn! • Scripts -> automations! • Workflow – stitch stactions! • Close the loop – map events to automations! • Total audit & transparency! • Still DevOps friendly ! • All automations are code in repositories! 7/21/14! © 2014 StackStorm, Inc.! Confidential!
- 28. Technical Details! • Centralized view (federated) into automations! • Audit trail and RBAC access controls! • Infrastructure as code! • Full APIs, configurations as code! • Collaboration inherent! • Abstraction of automations for sharing! • Two way integration into collaboration including ChatOps! • Bi directional close relationship with monitoring! • StackStorm helps users determine where to put problem analysis – StackTach and others promising! • Facility for self learning! • Simple today headed towards controller synthesis approaches! 28! ! 7/21/14! © 2014 StackStorm, Inc.!

- 29. Example Use Cases! • OpenStack and hybrid management! • Facilitated troubleshooting! • Over time – automated resolution! • Multi-stage deployments! • Develop, stage, deploy for example! • Response to security events! • Post-hoc as opposed to real time! 29! ! 7/21/14! © 2014 StackStorm, Inc.!
