+
+When you open a support case, you must provide debugging information about your cluster to the Red Hat Support team. You can use the `must-gather` tool to collect diagnostic information for project-level resources, cluster-level resources, and {gitops-title} components. 
+
+[NOTE]
+====
+For prompt support, provide diagnostic information for both {product-title} and {gitops-title}.

+= Collecting debugging data for {gitops-title}
+
+Use the `oc adm must-gather` CLI command to collect the following details about the cluster that is associated with {gitops-title}:
+
+* The subscription and namespace of the {gitops-title} Operator.
+* The namespaces where ArgoCD objects are available and the objects in those namespaces, such as `ArgoCD`, `Applications`, `ApplicationSets`, `AppProjects`, and `configmaps`.
+* A list of the namespaces that are managed by the {gitops-title} Operator, and resources from those namespaces.
+* All {gitops-shortname}-related custom resource objects and definitions.
+* Operator and Argo CD logs.
+* Warning and error-level events.
+
+.Prerequisites
+* You have logged in to the {product-title} cluster as an administrator.
+* You have installed the {product-title} CLI (`oc`).
+* You have installed the {gitops-title} Operator.
+
+.Procedure
+
+. Navigate to the directory where you want to store the debugging information.
+. Run the `oc adm must-gather` command with the {gitops-title} `must-gather` image:
++
+[source,terminal]
+----
+$ oc adm must-gather --image=registry.redhat.io/openshift-gitops-1/gitops-must-gather-rhel8:v1.9.0
+----
++
+The `must-gather` tool creates a new directory that starts with `./must-gather.local` in the current directory. For example, `./must-gather.local.4157245944708210399`.
+
+. Create a compressed file from the directory that was just created. For example, on a computer that uses a Linux operating system, run the following command:
++
+[source,terminal]
+----
+$ tar -cvaf must-gather.tar.gz must-gather.local.4157245944708210399
+----
+
+. Attach the compressed file to your support case on the link:https://access.redhat.com/[Red Hat Customer Portal].
