obzev0 is a chaos engineering platform designed to help you test the resilience of your systems by simulating real-world failures. It allows you to define and execute chaos experiments to uncover weaknesses in your infrastructure and applications.

• Language: Go (for the controller and gRPC server), C (for the eBPF program).
• Frameworks/Libraries: Kubernetes client-go (for interacting with the Kubernetes API), gRPC (for communication between components), eBPF (for kernel space programming).
• Monitoring: Prometheus and Grafana for monitoring and visualization.

Obzev0 is built using a microservices architecture, with the following components:

• Controller: Responsible for watching Custom Resource Definitions (CRDs) representing chaos scenarios and dispatching work to the DaemonSet.
• DaemonSet: Runs on every node in the Kubernetes cluster and acts as a gRPC server. It executes the chaos scenarios and communicates with the eBPF program in the kernel space.
• eBPF Program: Written in C, it runs in the kernel space and is responsible for monitoring and manipulating network traffic for performance monitoring.
