Infrastructure for Kubernetes: Namespaces

What are Namespaces?

Namespaces provide a mechanism for isolating groups of resources within a single Kubernetes cluster. They are commonly used to separate workloads by environment (e.g., dev, staging, prod) or by team.

In Kloudfuse, the Namespaces screen helps you monitor resource usage, deployment counts, and workload status across all namespaces. Use it to scope your observability efforts by logical boundaries within a cluster.

Access the namespaces screen

Go to Infrastructure > Kubernetes > Namespaces.

Namespace Table Columns

Each row in the table displays key namespace attributes:

• Cluster – Cluster where the namespace exists

• Namespace – Unique Kubernetes namespace name

• Status – Current state of the namespace (e.g., Active)

• Age – Time since the namespace was created

• Usage

  • CPU – Real-time CPU usage across all workloads in the namespace
  • Memory – Real-time memory usage across all workloads in the namespace

• Entity Counts

  • Pods – Total number of running pods in the namespace
  • Deployments – Number of deployments in the namespace
  • Daemon Sets – Number of daemon sets associated with the namespace
  • Stateful Sets – Number of stateful sets defined in the namespace
  • Cronjobs – Number of cronjobs scheduled within the namespace

Filters

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

• Kubernetes Filter
• Facets Filter
• Additional Filter

Search, group, and sort

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

• YAML
• Logs
• Metrics
• Events

YAML

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

• 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.

• 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.

• 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 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.
