 - `MaxCSIVolumeCount`: Decides how many {{< glossary_tooltip text="CSI" term_id="csi" >}}
   volumes should be attached, and whether that's over a configured limit.
 
-- `CheckNodeMemoryPressure`: If a Node is reporting memory pressure, and there's no
-  configured exception, the Pod won't be scheduled there.
-
-- `CheckNodePIDPressure`: If a Node is reporting that process IDs are scarce, and
-  there's no configured exception, the Pod won't be scheduled there.
-
-- `CheckNodeDiskPressure`: If a Node is reporting storage pressure (a filesystem that
-   is full or nearly full), and there's no configured exception, the Pod won't be
-   scheduled there.
-
-- `CheckNodeCondition`: Nodes can report that they have a completely full filesystem,
-  that networking isn't available or that kubelet is otherwise not ready to run Pods.
-  If such a condition is set for a Node, and there's no configured exception, the Pod
-  won't be scheduled there.

 - `PodToleratesNodeTaints`: checks if a Pod's {{< glossary_tooltip text="tolerations" term_id="toleration" >}}
