What is Keymetrics
Monitoring service that listens to PM2
You use test to
avoid functional regression
Keymetrics offers you a way to
avoid performance regression

14. http://getkeymetrics.com/
How it works
• PM2 daemon sends metrics about your apps
• Data is ciphered in AES256 with pub/priv keys
Keymetrics stores and classifies data to give
you a clear overview of what’s going on

15. http://getkeymetrics.com/
Metrics / Features
Multi server overview
Server monitoring
WS/HTTP/TCP analytics
Error tracking
Alerts / Weekly reports
Memory Leak detection
CPU/Memory profiling

Science & Metrics
• Time frame between deployment
• Get metrics timeframe summary for every past
deployment and know performance / error /
computation evolution and compare
Every time you will deploy new code you will
get a performance diff report

18. http://getkeymetrics.com/
Smarter data
• Big data processing
• So many monitoring data, applying Big data
processing will provide you blazing reports
• Know when, why and where a performance
regression happened
• Commit revision

19. http://getkeymetrics.com/
Goal: Fullstack system
Production NodeJS runtime
Simple deployment system
App Performance management
Performance regression detection
