OCNE 2.x: "ocne cluster dump" Command To Collect Diagnostics Data in Oracle Cloud Native Environment

Following ocne cluster dump command can be used to collect diagnostic data in Oracle Cloud Native Environment 2.x version for debugging the issues.

ocne cluster dump -k <kubeconfig file> -m -d /<directory to save logs>

Above command has to be executed on the client workstation CLI node from which connect to the OCNE 2.x cluster for administration. "-m" flag is to collect the Kubernetes configmap details 

Below is snippet of above command and files it collects

# ocne cluster dump -k /root/.kube/kubeconfig.mycluster -m -d /ocne-logs

INFO[2025-07-13T16:16:56-07:00] Cluster dump successfully completed, files written to /ocne-logs 

Following directories/files will be created in the location specified for collecting ocne cluster dump logs
