ℹ️ What is CortexBrain ?

CortexBrain is an ambitious open-source project designed to build an intelligent, lightweight, and highly efficient monitoring platform for distributed cloud and hybrid (cloud–edge) workflows. By leveraging the power of eBPF, CortexBrain can successfully manage networking and observability in a distributed cluster, limiting resource waste and improving overall performance.

Comprehensive information about CortexBrain’s core architecture, installation, and practical applications is available in the Official Documentation and on the CortexFlow blog.

⚡ Why CortexBrain ?

• 🔎 Deeper Insights: CortexBrain integrates eBPF with the KubeAPI to produce deeper kernel-level insights of your system

• 🚁 No sidecar overhead: Sidecarless architecture that eliminates memory waste and processing overhead

• 🔒 Safety: The linux BPF Verifier ensures that all the programs are safe to run.A JIT compiler converts bytecode into native CPU instructions for optimal execution efficiency. CortexBrain can trace network traffic such as ingress (incoming) and egress (outgoing) TCP/UDP connections and apply policies directly at kernel level by attaching the programs in different hooks such as TC (traffic control) and XDP hooks. All the intercepted events are successfully propagated in the user space thanks to BPF maps.

🧑🏻‍🔬 Current Development Focus

Our current development efforts are dedicated to the following key features:

• 🌐 Open Telemetry Integration: Integrating the open telemetry stack to our metrics to produce industry standard metrics formats
• 📈 Metrics enhancement: Expanding the current metrics landscape to provide deeper system understanding
• 📊 DashBoard Integration: Delivering beautiful user centered data visualization from the collected metrics
• 📡 [Experimental] Cloud-Edge Multi-Cluster Integration: Enabling orchestration between hybrid cloud and edge environments
• 🧪[Experimental] GPU Observability: Introducing GPU tracing and monitoring capabilities to efficiently support AI/ML applications
