    Description

      1. Proposed title of this feature request
      Collecting iPerf data in OpenShift

      2. What is the nature and description of the request?
      Currently the support team rely on customers to perform the steps in the following KCS to collect iPerf data between Nodes and Pods in the OpenShift. This tool can be used to collect data in

      KCS currently used:
      https://access.redhat.com/solutions/6129701

      There should be a tool that is as easy as running commands similar to the following:
      ```

      1. Collect from Pod-to-Pod (same and different nodes)
        oc adm collect iperf node/<node> node/<node>
      1. # Collect on the Host-to-Host Network
        oc adm collect iperf node/<node> node/<node> --hostnetwork
        ```

      Pods should be started and perform iPerf tests. If the `--hostnetwork` flag is provided then this will run the communication between hosts and not over the VXLAN / GENEVE tunnels as is seen in pod-to-pod inter-node communication.

      3. Why does the customer need this? (List the business requirements here)
      Collecting iPerf data can be difficult and time-consuming. The support engineers have spent large amounts of time collecting iPerf data from different areas within OpenShift Clusters and would be greatly assisted with some tooling around this.

      4. List any affected packages or components.
