StatGo give you access to OS metrics like network interface bandwith, cpus usage ...
It supports FreeBSD, Linux, OSX & more, it's in fact a libstatgrab binding for Golang.
Tested on FreeBSD, OSX, Linux amd64, Linux arm.
You need at least libstatgrab 0.91, Debian & Ubuntu only have 0.90 ...
On Debian/Ubunt & OSX, you can simply install libstatgrab with the usual commands:
./configure --prefix=/usr/local
make
sudo make install
You may have to set CGO_LDFLAGS and CGO_CFLAGS environment according to your path:
export CGO_CFLAGS=-I/usr/local/include
export CGO_LDFLAGS=-L/usr/local/lib
Note: On OSX you need to install gcc to access cgo.
