The cluster collector leverages Google’s cadvisor. This is the de-facto standard for container metrics collection. Thus, for now, we are bound by it to what can be supported.
And they do not support ARM out of the box.
Our priority is to support all enterprise environments and cover all key use cases. There is still some work here to do for us, that’s why we can not dedicate any time on ARM support. But we made the cluster collector for a reason open source and available on GitHub. So that everyone can have their go at it and adapt it to their needs.
Thus, feel free to follow the advice in the GitHub issue and build your own ARM packages.
