+  categoryDescription: |
+    CPU hog contains chaos to disrupt state of kubernetes resources. Experiments can inject a cpu skipe on a node where the application pod is scheduled.
+    - Causes (forced/graceful) cpu hog on a perticular node where the application deployment is available.
+    - After test the recovery should be manual of the application pod and node in case they are not in appropriate state.
