+= Storing and retrieving Argo CD logs
+
+You can use the Kibana dashboard to store and retrieve Argo CD logs.
+
+.Prerequisites
+
+* The {gitops-title} Operator is installed in your cluster.
+* The {logging-title} is installed with default configuration in your cluster.
+
+.Procedure
+
+. In the {product-title} web console, go to the {rh-app-icon} menu -> *Observability* -> *Logging* to view the Kibana dashboard. 
+
+. Create an index pattern.
+
+.. To display all the indices, define the index pattern as `pass:[*]`, and click *Next step*.
+
+.. Select *@timestamp* for *Time Filter field name*.
+
+.. Click *Create index pattern*.
+
+. In the navigation panel of the Kibana dashboard, click the *Discover* tab.
+
+. Create a filter to retrieve logs for Argo CD. The following steps create a filter that retrieves logs for all the pods in the `openshift-gitops` namespace:
+
+.. Click *Add a filter +*.
+
+.. Select the *kubernetes.namespace_name* field.
+
+.. Select the *is* operator.
+
+.. Select the *openshift-gitops* value.
+
+.. Click *Save*.
+
+. Optional: Add additional filters to narrow the search. For example, to retrieve logs for a particular pod, you can create another filter with `kubernetes.pod_name` as the field.
+
+. View the filtered Argo CD logs in the Kibana dashboard.
