Gohai
Gohai is a tool which collects an inventory of system information. It aims to implement some parts of features from facter and ohai. It's forked from Kentaro Kuribayashi's verity.
Usage
Gohai will build and install with go get. We require at least Go 1.7.
go get github.com/DataDog/gohaiRunning it will dump json formatted output:
$ gohai | jq .

How to build
Just run go build!
Build with version info
To build Gohai with version information, use make.go:
go run make.goIt will build gohai using the go build command, with the version info passed through -ldflags.
Updating CPU Information
Some information about CPUs is drawn from the source of the util-linux utility lscpu.
To update this information, such as when new processors are released, run
python cpu/from-lscpu-arm.py /path/to/lscpu-arm.c > cpu/lscpu_linux_arm64.go
