Hello,
I want to get custom metrics (cpu utilization percentage) from the
prometheus-adapter.
I've used helm to install the prometheus-adapter file with the conf file
I've attached and then when I execute: kubectl I get this:
{"name":"pods/malakas","singularName":"","namespaced":true,"kind":"MetricValueList","verbs":["get"]}
{"name":"namespaces/malakas","singularName":"","namespaced":false,"kind":"MetricValueList","verbs":["get"]}
but when I execute: kubectl get --raw
"/apis/custom.metrics.k8s.io/v1beta1/namespaces/default/pods/*/malakas" |
jq .
{
"kind": "MetricValueList",
"apiVersion": "custom.metrics.k8s.io/v1beta1",
"metadata": {
"selfLink":
"/apis/custom.metrics.k8s.io/v1beta1/namespaces/default/pods/%2A/malakas"
},
"items": []
}
Can anyone help me solve this issue in order not to get zero items?
Thank you in advance
