Weird! For reference one VM I run on only has 1 GB of memory, and Netdata uses 100-200 MB. Could be something going on with UnRAID though. Definitely some sort of bug I’d think, since normally resource usage should be very low across the board.

That’s strange, I’ve run it fine on some very underpowered hardware. Are you adding a specific monitoring integration with it, or just out of the box settings?

As others stated, you can run and access the interface locally (or setup your own reverse proxy) for free. Their Cloud dashboard is also free for up to 5 nodes. They recently added a flat-rate “Homelab” plan as well, if you want to remove the limit. It’s all quite usable for $0 otherwise though!

I’m a huge fan of Netdata, very configurable and monitors just about anything you could want. Great interface and alerts too - https://www.netdata.cloud/
