Installing BEATS on a AARCH Linux Machine

I downloaded the Linux 64 bit topbeats.zip file extracted and tried to execute on a linux aarch machine . The binaries is not supported.

-bash: ./topbeat: cannot execute binary file: Exec format error

uname -a is Ubuntu SMP Tue Aug 11 15:39:31 UTC 2015 aarch64 aarch64 aarch64 GNU/Linux

How can I install topbeats in this aarch64 machine

So you downloaded topbeat-1.1.1-x86_64.tar.gz? That's for x86, not ARM64. You need to obtain a Go compiler for your machine (probably by building it yourself) and compile Topbeat.
