At time of writing elastic.co does not provide ARM builds for raspberry. This tutorial describes how to compile e.g. filebeat and run in on Raspberry Pi3.
You'll need Git, Go (>1.8) and Python with virtualenv.
After spinning-up your Raspberry Pi and registering an account at slushpool:
sudo apt-get install automake autoconf pkg-config libcurl4-openssl-dev libjansson-dev libssl-dev libgmp-dev make g++ gitgit clone https://github.com/tpruvot/cpuminer-multicd cpuminer-multi./autogen.sh./build.sh./cpuminer --help./cpuminer -u slashpool_user_name.slashpool_worker -p pass -a sha256d -o stratum+tcp://stratum.slushpool.com:3333 -t cputhreads
