aksarav / kube-node-usage Goto Github PK

We would like to see what the requests/limits are. We can see it by individually describing our nodes, but it would be really nice to integrate that into this tool.

Thanks!

As the title says, when I run any command it says
"Failed to execute the Kubectl get nodes command"

This is a kubernetes running on oracle cloud, with 3 nodes.
If I run kubectl get nodes I get the correct info, but running the python script I get the error.

Hi,
I got the following error when running command:

python3 kube-node-usage.py --cpu --sort=usage

"Failed to execute the Kubectl get node command"

Please note that I'm able to successfully execute the command:

kubectl get nodes

Thanks for your support.

Hello,

I would like to "filter by label". Sadly the usage or syntax is unclear to me. Can you perhaps provide a few examples?

I can't filter on standard EKS node labels like e.g. failure-domain.beta.kubernetes.io/zone=eu-central-1b or similar.

For example, this does not work:

KubeNodeUsage -filterlabels="failure-domain.beta.kubernetes.io/zone=eu-central-1b"

Working with: Version: 3.0.1

Thanks,

Phil.

I think it is best practice to add the build results to .gitignore to prevent accidental commits and repository bloat.
To make discovery of the current artifacts easier they could be attached to a github release and the 'release' folder removed from git. (You may want to rewrite the history to reduce the size of the git repository.)

Variables ending with inmb starting here should be suffixed with ingb since you devide the Ki value by 1024 twice, which gives GiB.

Tested on Linux: It seems the application can be exited with "q" or ctrl-c while it states 'press any key to exit'. Space and return do not work.

Can you do it for pods? Like limits request and usage for per pod in namesapce?

i download git repo and trying to run lib from release folder but it is not running.
from where we can get python code.

or please update installation steps.

Hi,

Just ran the disk command with: python kube-node-usage.py --disk but it fails with the following error:

# Kube-Node-Usage
# Release 2.0.0
# https://github.com/AKSarav/Kube-Node-Usage

Traceback (most recent call last):

From the kubectl get nodes -o json command output; here is an example of the returned values:

                "allocatable": {
                    "cpu": "40",
                    "ephemeral-storage": "50977832921",
                    "hugepages-1Gi": "0",
                    "hugepages-2Mi": "0",
                    "memory": "65491060Ki",
                    "pods": "110"
                },
                "capacity": {
                    "cpu": "40",
                    "ephemeral-storage": "51175Mi",
                    "hugepages-1Gi": "0",
                    "hugepages-2Mi": "0",
                    "memory": "65491060Ki",
                    "pods": "110"
                },

Is this an issue with the k8s format?

For information, here is the version of k8s:

kubectl version
Client Version: version.Info{Major:"1", Minor:"25", GitVersion:"v1.25.4", GitCommit:"872a965c6c6526caa949f0c6ac028ef7aff3fb78", GitTreeState:"clean", BuildDate:"2022-11-09T13:36:36Z", GoVersion:"go1.19.3", Compiler:"gc", Platform:"linux/amd64"}
Kustomize Version: v4.5.7
Server Version: version.Info{Major:"1", Minor:"22", GitVersion:"v1.22.7+k3s1", GitCommit:"8432d7f239676dfe8f748c0c2a3fabf8cf40a826", GitTreeState:"clean", BuildDate:"2022-02-24T23:03:47Z", GoVersion:"go1.16.10", Compiler:"gc", Platform:"linux/amd64"}

Hope this will help.
