Hello,
Thank you for your reply.
Our cluster cannot use "kubectl top" command as the message shows "the server is currently unable to handle the request (get nodes.metrics.k8s.io)",
so I put only the result of "kubectl describe node" below.

[root@master01 ~]# kubectl describe node | sed -n -e '/Total/,/Events/p' -e 's/Name:/\n---:>&/p'

What should I do to improve the cp4d performance more?
Thank you,

Hi,
Your saturation is very high (see my test cluster for comparison, look at the scale difference) , what is the configuration of your cluster?
Can you please share the outputs of:
kubectl top node
kubectl describe node | sed -n -e '/Total/,/Events/p' -e 's/Name:/\n---:>&/p'
Can you explain what you mean by 'Our Cloud Pak for Data web console is always loading status' - are you saying its not performing well ?

Hello
Our Cloud Pak for Data web console is always loading status, so I reviewed its resource staus.
Watching it on grafana, I am worried about Memory satulation showing the high rate.
Each of colour in the attached photo shows each of master/worker nodes, and I don't use swap on all nodes.
It seems that other resource status such as CPU utilisation and Disk IO utilisation is not problem.
It is between 10 and 30 percent on average.
What brings this status? Is there something I have to do to improve memory satulation more?
Warm regards,
Chris
