How to get full memory / RAM in GO?

Question

How can I get the total amount of memory / RAM connected to the system in Go? I want to use native code only if possible. I found a library that wraps the linux sysinfo command. Is there a more elegant way?

Answer 1

Besides runtime.MemStats, you can use gosigar to monitor system memory.

Answer 2

cgo and linux solution

package main // #include <unistd.h> import "C" func main() { println(C.sysconf(C._SC_PHYS_PAGES)*C.sysconf(C._SC_PAGE_SIZE), " bytes") }
