      If a `must-gather` archive features a custom namespace directory ending with the suffix `nodes`, the Performance Profile Creator tool fails to analyze the archive. This occurs because of the tool's search logic, which incorrectly reports a multiple matches error. As a workaround, rename the custom namespace directory so that it doesn’t end with the `nodes` suffix, and run the tool again.

      This is a clone of issue OCPBUGS-60218. The following is the description of the original issue:
      —
      Description of problem:

      $ podman run --entrypoint performance-profile-creator -v "/root/ppc/must-gather.local.3879427019288622939/":/must-gather:z registry.redhat.io/openshift4/ose-cluster-node-tuning-rhel9-operator:v4.18 info --must-gather-dir-path /must-gather level=info msg="Nodes names targeted by master pool are: " level=info msg="Multiple matches for the specified must gather directory path: /must-gather and suffix: nodes" Error: failed to parse the cluster data: failed to load node's GHW snapshot: can't obtain the node path worker2.ocp4.terryhu.cc: Multiple matches for the specified must gather directory path: /must-gather and suffix: nodes.  Expected only one performance-addon-operator-must-gather* directory, please check the must-gather tarball

      Version-Release number of selected component (if applicable):

      4.18

      How reproducible:

      100%

      Steps to Reproduce:

          1. Collect must-gather
    2. Create a namespace that has "nodes" as its suffix, such as
$ mkdir /root/ppc/must-gather.local.3879427019288622939/quay-io-openshift-release-dev-ocp-v4-0-art-dev-sha256-a81f2df09a1b9a7ed63a20ced2182b9ba00a4b0ce49a8598d167ba900c87b12a/namespaces/three-nodes     
    3. Run the PPC info

      Actual results:

      Multiple matches for the specified must gather directory path: /must-gather and suffix: nodes.  Expected only one performance-addon-operator-must-gather* directory, please check the must-gather tarball

      Expected results:

      The PPC should only filter the "nodes" under cluster-scoped-resources/core, not cluster-scoped-resources.
