Flux:A New Approach to System Intuition
Target:
understand in real time what effect a variable is having on a subset of request traffic during a Chaos Experiment
We require a tool that can give us this holistic understanding of traffic as it flows through our complex, distributed system
requirements:
- Realtime data
- Data on the volume, latency, and health of requests
- Insight into traffic at network edge
- The ability to drill into IPC traffic
- Dependency information about the microservices as requests travel through the system
Pain Suit: As a microservice experiences failure, the corresponding electrodes cause a painful sensation.

The inter-region traffic from victim to savior increases while the savior region scales up. At that point, we switch DNS to point to the savior region. For about 10 seconds you see traffic to the victim region die down as DNS propagates. At this point, about 56 seconds in, nearly all of the victim region’s traffic is now pointing to the savior region
