k8s 可视化性能监控工具

ktop

A visualized monitoring dashboard for Kubernetes.

kubectl also has top subcommand, but it is not able to:

• Watch usages regularly for Pod/Node
• Compare the usage of Pod resources with Node or limits/requests

ktop resolves these problems and has a more graphical dashboard.

Installation

For MacOS:

$ brew tap ynqa/ktop
$ brew install ktop

From source codes:

$ git clone git@github.com:ynqa/ktop.git
$ go build ktop.go
