ktop

ktop [options]

ktop is a terminal UI monitoring tool for Kubernetes clusters, similar to htop for Linux. It provides real-time visualization of cluster resource usage including CPU, memory, disk, and GPU across nodes and pods.
The TUI displays a cluster overview with total resources and aggregate utilization, per-node metrics with CPU, memory, and pod counts, and a sortable list of pods with resource consumption and restart counts. Metrics update every 2 seconds by default.

Requires a working kubectl configuration and metrics-server deployed in the cluster. GPU monitoring requires appropriate drivers and device plugins.

ktop was created by Vladimir Vivien (vladimirvivien) and is written in Go. It was inspired by classic Unix monitoring tools like top and htop, adapted for Kubernetes cluster monitoring.
