Monitoring Kubernetes managed by Rancher

One more time for today - Good day to you.

Well, we have a running k8s cluster, which is managed with Rancher. I read some blog posts showing the Dynatrace Managed monitoring a Kubernetes environment.

So, I took all VMs, which are involved in the Kubernetes cluster like

kube-nfs
kube-etcd
kube-nodes (which are the docker hosts running the dockerized applications)

Well, I see that Dynatrace notices the Docker containers but I do not see anything about a Kubernetes environment. I see VMware, AWS or Azure environments as themselves but no information but no information or at least no signs from some k8s cluster member or from Rancher or ....

So, I think, I missed something, but what is wrong?

Thank you in advance,

Jan

You did everything correctly, there is no specific k8s dashboard.

If you want additional metrics for the health of the k8s cluster itself, not only the pods running there, you can try the Kubernetes ActiveGate Plugin which is currently in EAP.

Good day to you, @Patrick H.,

ok, thank you for your answer. Well, then should I wait for the traffic and see, what the AI of Dynatrace will show then.

Is there any advance in installing the OneAgent by docker instead of installing it native on a kube host?

Best regards,
Jan

Installing them on the kube hosts is fine, there won't be a difference in data when you deploy it via an image.
