Mini-Training: Measure Anything Optimize Everything
- 2. Make decisions based on a scientific approach Build a scientific approach based on what is known of « real life » aka « Production » “You can’t manage what you don’t measure.” W. Edwards Deming, Peter Drucker Measure anything, Optimize Everything
- 3. • Different levels of knowledge: • Level 0 : no monitoring, metrics or logs. Features are defined based on feeling, intuitions. This is a blind approach. • Level 1 : metrics and logs are reviewed post dev. Success is defined based on real events and failures. • Level 2 : decisions and actions are deducted from metrics and statistics. We measure to validate the results of our actions. Where are we ? Get Knowledge
- 4. • How do we know something is wrong ? – Customer Service: calls from customers – Error Logs • How do we know everything is ok ? – … Production Knowledge
- 5. • How do we know if the new killer feature is used ? • How do we know how efficient is our code ? Feature Knowledge
- 6. • Define a metrics-driven process to : – Know applications in real life – Monitor – Evolve in a measured and verified way Objectives
- 7. 1. Ask a question 2. Set an idea 3. Establish a prediction along this idea 4. Experiment to test this prediction 5. Analyse results to validate or reject the idea 6. Share results 7. Repeat Scientific approach
- 8. • This approach needs a deep instrumentation of the whole platform : – Aggregate data from many sources – Measure – Monitor along time – Analyse it in real-time or at posteriori – Decide and act accordingly Measure anything
- 10. • Tools to monitor network and machines : – Nagios/Centreon – SCOM • Metrics : – Server status – Front / Service status – Network Bandwidth – … Technical Monitoring
- 11. • Hard to manage : – Related to business – Change as business changes (often) – Can’t be easily automated, not easily catchable • Examples : – Login successful/failed – Bets placed Sport / Turf – Casino transactions – Challenge subscriptions – Banners displayed What about application ?
- 12. Application monitoring = Business monitoring • Each application knows its own business – Define and report their own metrics • Examples : – On Turf, how many races are on sale. – On Sport, how many time it takes to place a bet. – On Casino, how many games are currently available. – … Application monitoring
- 13. 13 All is about Metrics High Level Real Time Fast issue detection Confidence Metrics should be part of every feature. Simple Accessible Required Pertinent “Measure what is measurable, and make measurable what is not so.” Galileo Galilei
- 14. • Dashboards : – Dev oriented – Display metrics – Inform if all is OK – Emit alerts – Real time production status Application monitoring
- 15. Dashboards Level 2 (at Etsy)
- 16. • If we can measure, we can optimize – Reduce Errors logs – Reduce response time – Optimize call numbers – Remove dead code/feature – Increase offer/bet placed – … – Overall Quality 16 Finally : Optimize Everything
