+description: |-
+  node-problem-detector aims to make various node problems visible to the
+  upstream layers in the cluster management stack. It is a daemon that runs
+  on each node, detects node problems and reports them to apiserver.
+  node-problem-detector can either run as a DaemonSet or run standalone.
+  Now it is running as a Kubernetes Addon enabled by default in the GCE cluster.
