Manage cluster nodes

In a multi-node deployment, you can check whether cluster nodes are running from the Nodes page. In a single-node deployment, you can check how well your server is running from the Nodes page.

You can access the Nodes page from the Menu icon: (Screen capture of the menu icon).

Deployment type Available information
Single-node deployment

For the server, you can see the following information:

  • The IP address of the server
  • How many CPU cores the server is using
  • The amount of memory (GB) the server is using
  • The amount of disk storage (GB) the server is using
Example of the data that is displayed for Storage nodes on the Nodes page of IBM Data Platform Manager.
Tip: Do you need more detailed information?
  • If you click the server name, you can see the CPU, storage, and memory consumption for the server over the last 20 minutes.
    Example of the data that is displayed when you click on the server name.
  • If you expand the server name, you can see the operating system partition and disk partition where the server is running. You can also see the size of the partition and how much of the partition is currently in use.
    Example of the data that is displayed when you expand the server name.
Multi-node deployment For each node in the cluster, you can see:
  • The IP address of the node
  • Whether the node is running or down
  • How many CPU cores the node is using
  • The amount of memory (GB) the node is using
  • The amount of disk storage (GB) the node is using
Example of the data that is displayed for Storage nodes on the Nodes page of IBM Data Platform Manager.
Tip: Do you need more detailed information?
  • If you click the node name, you can see the CPU, storage, and memory consumption for the node over the last 20 minutes.
    Example of the data that is displayed when you click on a node name.
  • If you expand the node name, you can see the operating system partition and disk partition where the node is running. You can also see the size of the partition and how much of the partition is currently in use.
    Example of the data that is displayed when you expand a node.

Node outages

This information is specific to a cluster deployment. In a multi-node deployment, Kubernetes is designed to handle node outages, so you can still use IBM® Db2® Event Store and IBM Watson™ Studio Local if some of your nodes are down. However, if a node is down, you should attempt to diagnose and resolve the problem to avoid outages if other nodes fail.

Contact IBM Software Support if you cannot determine why the node failed or how to restart the node.

If you are running a single-node deployment, contact IBM Software Support if you cannot determine why your server failed or how to restart the server.
