Hi !
There is probably an issue with how the metric is captured by the agent here.
Before we dig any further are also a few unexpected things in your configuration that would be nice to fix:
-Delastic.apm.cpu_count=2
: I don't know this config option, do you know where it comes from ?-Delastic.apm.server_url=https://localhost:8200
will make the agent send data tolocalhost
which means unless there is an apm-server running within the container it's quite unlikely to send data anywhere.
