Inspektor Gadget
CNCF eBPF-based observability for Kubernetes: gadgets for tracing DNS, TCP, exec, and security events from kubectl.
Why it is included
Developer-friendly bridge between kubectl workflows and kernel-level visibility for debugging and security.
Best for
Platform engineers troubleshooting K8s networking and syscall-level behavior without bespoke BPF code.
Strengths
- CNCF sandbox
- kubectl integration
- Gadget ecosystem
Limitations
- Kernel/BTF requirements; not a full SIEM
