Why can't metric UI use apm metric data?

I found results in Metrics Explorer.



The kubernetes.pod.* fields must be generated by metricbeat.
We will not deploy metricbeat for the time being. I don’t need much data.
Do you plan to add service performance indicators(cpu usage and memory usage) to apm metric?


If there are cpu usage and memory usage data, then apm metric page data can be more abundant.
