Infrastructure for Kubernetes: Nodes

What are Nodes?

Nodes are the worker machines in a Kubernetes cluster. Each node runs container workloads and includes components like the container runtime, kubelet, and kube-proxy.

In Kloudfuse, the Nodes screen helps you monitor the health, capacity, and performance of all Kubernetes nodes. Use it to check CPU and memory usage, scheduling status, roles, and node-level failures.

Access the nodes screen

Go to Infrastructure > Kubernetes > Nodes.

Node Table Columns

Each column in the table displays key node attributes:

  1. Cluster – Cluster where the node is deployed

  2. Node – Unique name of the node

  3. Status – Node condition indicators:

    • Ready: Node is healthy and accepting workloads

    • NotReady: Node is unreachable or unhealthy

    • Unknown: Node state cannot be determined

  4. Schedulable – Indicates whether the node is currently accepting new pods (cordoned or not)

  5. Age – Time since the node joined the cluster

  6. Kubelet Version – Version of the kubelet process running on the node

  7. Roles – Node roles such as control-plane, worker, or infra

  8. CPU

    • Total – Total number of CPU cores on the node

    • Allocable – CPU capacity available for scheduling pods

    • Used – Real-time CPU usage by active workloads

  9. Memory

    • Total – Total memory capacity on the node (GiB)

    • Allocable – Memory available to pods after system reservations

    • Used – Real-time memory consumption by pods and system processes

Filters

Kloudfuse provides three categories of filters to scope your results precisely.

Search, group, and sort

Click any row to open the node detail pane.

Node Detail pane

Each node view includes multiple tabs for deeper observability. The node detail pane contains four tabs. These include:

YAML

Use the YAML tab to inspect the live configuration of your Kubernetes resource.

infrastructure kubernetes pods detail yaml
YAML Display pane

  • View full manifest details for pods, deployments, nodes, etc.

  • Quickly detect misconfigurations or missing annotations.

  • Copy YAML for debugging or backup purposes.

Logs

Use the Logs tab to inspect real-time application and system logs for a selected Kubernetes resource.

Logs panel view
Logs Display pane

  • Select specific containers to view logs at a granular level.

Log search supports full-text match, tag selection, and time-range filters.

Metrics

The Metrics tab displays real-time CPU, memory, network, and disk usage for the selected resource.

Metrics panel showing CPU and memory trends
Metrics Display pane

  • Visualize container-level metrics and trends.

  • Correlate spikes or anomalies with logs or events.

  • Use chart time selectors to view metrics at different intervals (e.g., last 5m, 1h, 24h).

Events

Use the Events tab to view scheduled updates, restarts, warnings, or failed operations for a Kubernetes resource.

Events Display pane

  • Events include timestamps and source controllers.

  • Use this tab to diagnose readiness failures, scaling issues, or resource evictions.

  • Combine with Logs and Metrics for faster RCA.
