# Go sigar [![Build Status](https://travis-ci.org/elastic/gosigar.svg?branch=master)](https://travis-ci.org/elastic/gosigar) [![Build status](https://ci.appveyor.com/api/projects/status/4yh6sa7u97ek5uib/branch/master?svg=true)](https://ci.appveyor.com/project/elastic-beats/gosigar/branch/master)


## Overview

Go sigar is a golang implementation of the
[sigar API](https://github.com/hyperic/sigar).  The Go version of
sigar has a very similar interface, but is being written from scratch
in pure go/cgo, rather than cgo bindings for libsigar.

## Test drive

    $ go get github.com/elastic/gosigar
    $ cd $GOPATH/src/github.com/elastic/gosigar/examples/ps
    $ go build
    $ ./ps

## OS Specific Notes

### FreeBSD

Mount both `linprocfs` and `procfs` for compatability. Consider adding these
mounts to your `/etc/fstab` file so they are mounted automatically at boot.

```
sudo mount -t procfs proc /proc
sudo mkdir -p /compat/linux/proc
sudo mount -t linprocfs /dev/null /compat/linux/proc
```
