+## Test support bundle image supports node collection timeout
+
+**Given** Run the support bundle manager image (version 0.0.38 or later) using Docker.
+```
+> docker run -it longhornio/support-bundle-kit:v0.0.38 bash
+```
+
+**When** Execute `support-bundle-kit manager --help`.  
+**Then** The help menu displays the `--node-timeout` option.
+```
+> support-bundle-kit manager --help | grep node-timeout
+      --node-timeout duration       The support bundle node collection time out
+```
+
+## Test `support-bundle-node-collection-timeout` setting
+
+**Given** Simulate the node bundle blockage by patching the [rancher/support-bundle-kit](https://github.com/rancher/support-bundle-kit) code base and create an image.

+
+**When** Generate a support bundle using Longhorn UI.  
+**And** Monitor the support bundle manager logs.
+```
+> kubectl -n longhorn-system logs `kubectl -n longhorn-system get pod -l app=support-bundle-manager --no-headers | awk '{print $1}'` -f
+```
+
