@Rafal_Radziejewski For the first problem with the Pods not displaying data....
When you click through to "View Metrics" for a pod, are the charts empty? If they are empty, can you run the following query in the Kibana dev console and post the response?
POST metricbeat-*/_search?terminate_after=1
{
"query": {
"match": {
"metricset.name": "pod"
}
},
"size": 1
}
What I suspect is happening is that the kubernetes.pod.uid field is not being set properly in the agent but I would need to see some sample data to know for sure.
For the Docker metrics, I talked with @exekias and he explained that the percentage reported is all the cores combined. If you have 8 cores then it could report up to 800%. Since he's mentioned here, he can follow up with additional questions.
