The Prometheus adapter keeps only some metrics and does renaming on them, please take a look here: https://github.com/DirectXMan12/k8s-prometheus-adapter/blob/master/docs/format.md
Thanks @stefanprodan . According to document you mentioned, "container_network_receive_bytes_total " suppose to be kept by Prometheus adapter, am i correct? it's not the case for me, i couldnt see this metrics
[xyz@master ~]$ kubectl get --raw /apis/custom.metrics.k8s.io/v1beta1|jq .|grep network "name": "pods/network_tcp_usage", "name": "pods/network_udp_usage",
Thanks
Hello, I'm running kubernetes 1.10, and followed instruction here and installed metrics server, custom-metrics-api, and prometheus. I'm able to do autoscaling based on http_requests, but i can not do that based on container_network_receive_bytes_total, i noticed that httprequests metrics exposed at "/apis/custom.metrics.k8s.io/v1beta1", see output below: [xyz@master k8s-prom-hpa]$ kubectl get --raw /apis/custom.metrics.k8s.io/v1beta1|jq .|grep http_requests "name": "pods/http_requests_count", "name": "pods/http_requests", "name": "namespaces/http_requests", "name": "jobs.batch/http_requests", "name": "pods/http_requests_sum", "name": "jobs.batch/http_requests_bucket", "name": "jobs.batch/http_requests_count", "name": "jobs.batch/http_requests_sum", "name": "namespaces/http_requests_count", "name": "namespaces/http_requests_sum", "name": "pods/http_requests_bucket", "name": "namespaces/http_requestsbucket",
but this is the case for "container_network_receive_bytes_total"
_[xyz@master k8s-prom-hpa]$ kubectl get --raw container_network_receive_bytes_total|jq .|grep network "name": "pods/network_udp_usage", "name": "pods/network_tcpusage",
In Prometheus , i can see "container_network_receive_bytestotal" with data, actually all the metrics start with "container" in Prometheus didn't get exposed at /apis/custom.metrics.k8s.io/v1beta1..., any help is really appreciated
