Lens not showing node memory usage, CPU and disk works fine (on Raspberry Pi cluster)
Describe the bug The cluster is four Raspberry Pi 5 running Debian 64-bit lite. I let Lens install prometheus and node-exporter, and for the nodes tab I see usage except on the memory row (see screenshot 1). The overall view (screenshot 2) works fine.
To Reproduce Steps to reproduce the behavior:
- Go to the nodes tab
Expected behavior The memory "bar" being colored.
Screenshots
Screenshot 1a (no memory usage showing):
Screenshot 1b (after clicking on a node):
Screenshot 2 (overall dashboard looking fine):
Environment (please complete the following information):
- Lens Version: 2024.1.170738-latest
- OS: [e.g. OSX] macOS 14.2.1 (M2)
- Installation method (e.g. snap or AppImage in Linux): DMG file

Additional context I hope the screenshots explain enough of the issue. I have tried running a stress test to make a pod use around 4GB of memory, but it still didn't show up on the memory bar.
Hello MasterWayZ,
Thank you for reporting this issue!
I want to inform you that we working on it already.
