Welcome to Cloud Native FM and our short segment Cloud Native Wisdom. In this episode, I speak with Qasim Sarfraz (Inspektor-Gadget maintainer) to answer a common question: If I already have Prometheus, Grafana, and OpenTelemetry, do I still need Inspektor-Gadget? Tell us: what signals would you want Inspektor-Gadget to add to your autoscaling logic? Drop your configs/snippets and we’ll feature them in a follow-up demo. TL;DR - Inspektor-Gadget is not a replacement for Prometheus/OpenTelemetry — it’s a flexible data-collection / observability framework that captures signals you often can’t get anywhere else (process-level, DNS, kernel/eBPF events, syscall traces). - Use Inspektor-Gadget to produce richer signals, enrich them with Kubernetes metadata, and forward them to Prometheus / OpenTelemetry or other backends. - Best pattern: collect → enrich → forward → decide. Feed Inspektor-Gadget outputs into your existing HPA/KEDA/VPA, Grafana alerts, or policy engines (OPA/Kyverno) for stronger autoscaling, forensic, and regulatory workflows.
