ntop is an open-source tool designed to provide clear and visual insights into the status of nodes and pods in your Kubernetes cluster. Leveraging Kubernetes' metrics server, ntop fetches and displays real-time CPU and memory utilization metrics in an easy-to-consume command-line interface.

• Go (1.16 or later)
• Access to a Kubernetes cluster
• Kubernetes configuration file (usually at ~/.kube/config)

Clone the repository and build the tool:

git clone https://github.com/devopswe/ntop
cd ntop
GOOS=linux GOARCH=amd64 CGO_ENABLED=0 go build -o ntop-linux-64-0.2.0

Ensure the metrics-server is installed on your cluster:

kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml

Note: If you encounter SSL/TLS errors, modify components.yaml to include the --kubelet-insecure-tls flag.

Run ntop:

./ntop-linux-64-0.2.0 --kubeconfig=path/to/your/kubeconfig

Optional flags:

• --pods: Switch to pods view.
• --countpods=<number>: Specify the number of pods to display (default is 10).

• Real-time CPU and memory usage metrics for nodes and pods.
• Toggle between node and pod views with ease.
• Customize the number of pods displayed.
• Simple and intuitive command-line interface.

• New live table display of nodes and pods.
• --pods flag to easily switch to pod metrics.
• --countpods flag to specify the number of pods displayed.
• Improved performance and reduced waiting times.
• Instantaneous pod data retrieval with the new concurrent structure.
• Cross-platform availability: Windows, Linux, MacOS (Intel & ARM).

Special thanks to @dbtek and @faruktoptas for their contributions!

• k8s.io/client-go and k8s.io/metrics for Kubernetes interaction.

Use go mod tidy to manage dependencies.

Our vision for ntop includes:

1. Modularization: Refactor for maintainability and scalability.
2. kubectl Plugin: Enhance accessibility and integration.
3. Enhanced Filtering: Customize data display based on user preferences.
4. Trend Analysis: Introduce historical data tracking and analysis.
5. Interactive UI: Develop a terminal-based interactive UI.
6. Support Additional Resources: Extend monitoring to more Kubernetes resources.
