## Common questions

### How do I enable NodeAgent runtime detection when installing Kubescape?

Use the Kubescape Helm chart and set capabilities.runtimeDetection=enable and alertCRD.installDefault=true in the kubescape namespace. Then wait for pods labeled app=node-agent to become ready.

### How can I watch alerts from NodeAgent after installation?

Run kubectl logs in the kubescape namespace for pods labeled app=node-agent with follow enabled. Alerts appear after the initial learning period completes.

### What performance impact does NodeAgent have on Kubernetes nodes?

It uses eBPF for kernel-level monitoring with minimal performance overhead. The README reports around 1 to 2 percent CPU overhead.

### What eBPF format does NodeAgent use for its gadgets?

NodeAgent uses image-based gadgets in the Inspektor Gadget image format.
