I have installed the Elasticsearch(8.16) and kibana(8.16) using RPMs in Centos vm.Also installed Metricbeats (8.16) in the centos vm using RPMS.
In the same vm i have kubernetes cluster and our application is running in the k3s cluster.I am trying to capture the kubernetes metrics and see that in Kibana dashboard.
Issue :
I am able to see the namesapce details in the dashboard but the pod, deployment fields i am getting as no data found. like this attached screenshot.
this is the content of the In the
/etc/metricbeat/modules.d/kubernetes.yml
Node metrics, from kubelet:
- module: kubernetes
metricsets:- node
- pod
- system
- volume

Below is the error message i am getting in the logs of Metricbeat :

Note : The Metricbeats is installed as RPM and not inside kubernetes cluster.But both are in same vm.
Please guide us fixing this issue , Thanks in advance.
