       in Pod GC Controller.
       For Attach Detach Controller, there's already a metric:
-      attachdetach_controller_forced_detaches
-      It is also useful to know how many nodes have taints. We can explore with [kube-state-metrics](https://github.com/kubernetes/kube-state-metrics) which generates metrics about the state of the objects.

+      There is also a `kube_node_spec_taint` in [kube-state-metrics](https://github.com/kubernetes/kube-state-metrics/blob/main/docs/node-metrics.md) that is a metric for the taint of a Kubernetes cluster node.
