MacOS: Cadvisor says it's running but there are no metrics using Agent Flow

[teekwan]

When observing Cadvisor status, it says "Healthy"

But, when trying to access the metrics path shown, it says 404:

These are two "docker_host" values I tried using but either acts the same as above:

A similar setup works on Ubuntu host.
And yes, the user running agent service is part of "docker" group and needs no sudo to perform docker commands.
This is Mac Mini M2 Sonoma v14.4.1 and I've used Brew to install grafana-agent-flow.

Thanks in advance!
