Monitoring the system node

Use CLI or web console to view information about nodes in Cloud Pak for Data System.

About this task

A node can be defined by its personality, state and status.

Personalities define the role of the node in the system and they are described in System nodes.

The node state determines its use in the system, not its health. Node state can be one of the following:
  • ENABLED - the node is used to run the applications
  • DISABLED - the node is not used to run the applications
  • ENABLING - node enablement is in progress
  • DISABLING - node disablement is in progress
  • UNMANAGED - the node is not managed by Platform Manager

You can also check the status of the node, which is its health, for example, OK, or WARNING.

Procedure

  • To display node state and personality, use the ap node command:
     ap node

  • You can also use the web console to view node information. Click Hardware overview
    In the Graphical view there is a graphical overview of the platform. You can view all nodes with their physical location in the rack. Next to a node there is an icon representing possible alerts. After clicking on it, you can view details in the View details section on the right side.
