Description
I have spend 2 days trying to figure out how to use the CRI-O metrics with Prometheus.
I give up I can not figure it out. Either the documentation is deprecated or the configurations are.
I followed the instructions given here: tutorials/metrics.md.
The exporter is running:
$ kubectl get all -n cri-o-metrics-exporter --kubeconfig IaC/k8s/tf/kube/config
NAME READY STATUS RESTARTS AGE
pod/cri-o-metrics-exporter-56855d56c8-jcv6z 1/1 Running 0 7h27m
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
service/cri-o-metrics-exporter ClusterIP 10.200.131.115 <none> 80/TCP 7h27m
NAME READY UP-TO-DATE AVAILABLE AGE
deployment.apps/cri-o-metrics-exporter 1/1 1 1 7h27m
NAME DESIRED CURRENT READY AGE
replicaset.apps/cri-o-metrics-exporter-56855d56c8 1 1 1 7h27m
The crio metrics configurations are in place:
$ cat /etc/crio/crio.conf.d/01-metrics.conf
[crio.metrics]
enable_metrics = true
metrics_port = 9090
I have added the scrape configurations on Prometheus and now I am getting the error:
Error scraping target: server returned HTTP status 404 Not Found
I do not know what I am missing. Is there anyone who maintains the metrics?
