I'm using Prisma Cloud Compute Edition 22.01.880 in a Kubernetes cluster. Under Radars > Settings > Network Monitoring, I have container and host network monitoring turned on. I deploy the Defenders to the Kubernetes nodes using a DaemonSet. When I look at the logs for the Defender, I see a lot of the following errors:
`failed to save iptables Twistlock defender completed with an error: exec: "iptables-save": executable file not found in $PATH exit status 1`
`failed to restore iptables Twistlock defender completed with an error: exec: "iptables-restore": executable file not found in $PATH exit status 1`
If I shell into the Defender pod, I cannot find any executables for `iptables-*`. And, I think that this is causing my Containers Radar to not show network connections.
Am I misconfiguring something? Or do the Defender images need the executables added from Palo Alto?

The error message below could be related to an issue with k8s kube proxy. Please consider reviewing the logs in the kube-proxy pods in kube-system namespace for clues and verify the logs from the defender pods are coming from /var/lib/twistlock/log/defender.log. If the kube-proxy logs do not provide any useful information you can recycle the kube-proxy pods to help clean things up as well. k8s will create new ones for you. If the logs from /var/lib/twistlock/log/defender.log on the defender do not provide any clues and restarting the kube-proxy pods do not help, please contact support so we can assist further.
