Monitoring nodes

You can get Kubernetes, cluster health, and node health information by monitoring CDW nodes.

  1. In the Welcome screen, click grid , and then select Manage.
    A list of dashboard groups appears:
  2. Click the nodes dashboard group.
    Names of the nodes dashboards in the group appear:
  3. In the list of nodes dashboards, click Node Details, and then set the node of interest: In datasource, set default for example; in Job, set kubernetes-service-endpoints for example; in Host, set the IP address of a host in the CDW cluster.
  4. Expand Quick CPU/Mem/Disk, and view the percentage of busy CPU, the percentage of average load over the past 5 minutes and over the last 15 minutes, and RAM used.
  5. On the right side of the dashboard, with Last 24 hours selected, for example, view the SWAP space used, root file system used, CPU cores used, and uptime of the node.
  6. Scroll down, expand Basic CPU/Mem/Net/Disk, and see graphs on the left showing metrics about high activity from various souces, such as a busy user or busy interrupt requests (IRQ), and a graph of packets received and transmitted by network traffic.
  7. On, the right, see graphs of basic memory and disk space use.
  8. In the list of nodes dashboards, click Cluster Totals to view cluster health in graphs and metrics over the past 24 hours, as indicated by Cluster Memory Utilization, Cluster CPU Utilization, Shared Services Node Count, and Compute Nodes Count.
  9. In the list of nodes dashboards, click Node Trends to view node health over the past 24 hours, as indicated by CPU Utilization, Load Average and CPU Count, Memory Utilization, and Disk Utilization.
