Flux-A New Approach to System Intuition

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.
