Open-source platform for end-to-end observability and AI-powered reasoning across distributed systems.
Build a complete observability platform that:
- Collects sparse telemetry from hosts and Kubernetes using eBPF
- Aggregates data through open-source pipelines (OpenTelemetry, Kafka, ClickHouse)
- Builds a unified knowledge graph of system architecture
- Reasons using GraphRAG and LLMs to:
- Explain components and dependencies
- Generate live architecture diagrams
- Auto-document infrastructure
- Answer natural language questions about security, performance, and architecture
brew install colima docker docker-compose
colima start --cpu 4 --memory 8git clone <your-repo-url> sds-ebpf
cd sds-ebpf
docker build -t sds-observer:latest -f docker/Dockerfile.agent .
cd docker && docker-compose uptail -f docker/output/events_*.json | jq .See full instructions: Quick Start Guide
What's Built:
- Sparse-sampling eBPF agent (60s on / 4min off)
- Monitors: processes, syscalls, network connections, containers
- User-space collector in Go
- JSON event output
- Docker setup for local macOS development
Documentation:
Try it:
cd agent
make build
sudo ./bin/sds-observer --output /tmp/sds-observer --verbosePlanned:
- OpenTelemetry Collector integration
- Kafka/Redpanda for streaming
- ClickHouse for event queries
- VictoriaMetrics for metrics
- Neo4j/Memgraph for graph storage
- ETL pipeline to build unified graph schema
- Phase 3: GraphRAG indexing, LLM training on architecture data
- Phase 4: Interactive diagrams with LLM explanations
- Phase 5: Auto-generated documentation and testing guides

This is a defensive security tool for observability and monitoring.
- ✅ Monitors system activity for understanding architecture
- ✅ No data exfiltration (local storage by default)
- ✅ Open-source and auditable
- ❌ Not for malicious use
- ❌ Does not harvest credentials or sensitive data
Note: Always review your organization's policies before deploying observability tools.
