Gathering debugging data

You can use the must-gather tool to collect data about the Custom Metrics Autoscaler Operator and its components, including the following items:

  • The openshift-keda namespace and its child objects.

  • The Custom Metric Autoscaler Operator installation objects.

  • The Custom Metric Autoscaler Operator CRD objects.

Gathering debugging data

The following command runs the must-gather tool for the Custom Metrics Autoscaler Operator:

$ oc adm must-gather --image="$(oc get packagemanifests openshift-custom-metrics-autoscaler-operator \
-n openshift-marketplace \
-o jsonpath='{.status.channels[?(@.name=="stable")].currentCSVDesc.annotations.containerImage}')"

The standard OKD must-gather command, oc adm must-gather, does not collect Custom Metrics Autoscaler Operator data.
Prerequisites

  • Access to the cluster as a user with the cluster-admin role.

  • The OKD CLI (oc) installed.

Procedure

  1. Navigate to the directory where you want to store the must-gather data.

    If your cluster is using a restricted network, you must take additional steps. If your mirror registry has a trusted CA, you must first add the trusted CA to the cluster. For all clusters on restricted networks, you must import the default must-gather image as an image stream by running the following command.

    $ oc import-image is/must-gather -n openshift

  2. Perform one of the following:

    • To get only the Custom Metrics Autoscaler Operator must-gather data, use the following command:

      $ oc adm must-gather --image="$(oc get packagemanifests openshift-custom-metrics-autoscaler-operator \
-n openshift-marketplace \
-o jsonpath='{.status.channels[?(@.name=="stable")].currentCSVDesc.annotations.containerImage}')"

      The custom image for the must-gather command is pulled directly from the Operator package manifests, so that it works on any cluster where the Custom Metric Autoscaler Operator is available.

    • To gather the default must-gather data in addition to the Custom Metric Autoscaler Operator information:

      1. Use the following command to obtain the Custom Metrics Autoscaler Operator image and set it as an environment variable:

        $ IMAGE="$(oc get packagemanifests openshift-custom-metrics-autoscaler-operator \
  -n openshift-marketplace \
  -o jsonpath='{.status.channels[?(@.name=="stable")].currentCSVDesc.annotations.containerImage}')"

      2. Use the oc adm must-gather with the Custom Metrics Autoscaler Operator image:

        $ oc adm must-gather --image-stream=openshift/must-gather --image=${IMAGE}
