Troubleshooting

Troubleshooting#

This guide provides steps to diagnose and resolve common issues with the AMD Network Operator.

Checking Operator Status#

To check the status of the AMD Network Operator:

kubectl get pods -n kube-amd-network

Collecting Logs#

To collect logs from the AMD Network Operator:

kubectl logs -n kube-amd-network <pod-name>

Using Techsupport-dump Tool#

The techsupport-dump tool collects system state and logs for debugging purposes. It can be run from any node in the cluster, including control plane nodes.

./tools/techsupport_dump.sh [-w] [-o yaml/json] [-k kubeconfig] <node-name/all>

Options:

  • -w: wide option

  • -o yaml/json: output format (default: json)

  • -k kubeconfig: path to kubeconfig (default: ~/.kube/config)

TechSupport Collects:#

  1. Kubernetes resources from the network-operator, nfd, and kmm namespaces, including:

    • Pods

    • DaemonSets

    • Deployments

    • ConfigMaps

    • NetworkConfig resources

  2. Pod logs from components such as:

    • Node Feature Discovery (NFD)

    • Kernel Module Management (KMM)

    • Network Operator (Data Plane, Metrics Exporter, CNI plugins)

  3. System-level diagnostics:

    • lsmod output (loaded kernel modules)

    • dmesg output (kernel ring buffer)
