npd

Introduction

node-problem-detector (npd for short) is an add-on that monitors abnormal events of cluster nodes and connects to a third-party monitoring platform. It is a daemon running on each node. It collects node issues from different daemons and reports them to the API server. The npd add-on can run as a DaemonSet or a daemon.

For more information, see node-problem-detector.

From December 30, 2020, the npd add-on in CCE will be automatically upgraded to the latest version. Containers with this add-on installed on each node will be restarted, but your services will not be affected. You can go to the Add-ons page on the CCE console to upgrade the add-on now. For details about how to upgrade the add-on, see Upgrading the Add-on.

We strongly recommend that you perform this upgrade. If you do not want to upgrade the add-on, you can submit a service ticket to cancel the automatic upgrade and perform the upgrade later.
