Package sysinfo is a Go library providing Linux OS / kernel / hardware system information. It's completely standalone,
has no dependencies on the host system and doesn't execute external programs. It collects only "inventory type"
information, things that don't change often.
## Code Example
```go
package main
import (
"encoding/json"
"fmt"
"log"
"os/user"
"github.com/zcalusic/sysinfo"
)
func main() {
current, err := user.Current()
if err != nil {
log.Fatal(err)
}
if current.Uid != "0" {
log.Fatal("requires superuser privilege")
}
var si sysinfo.SysInfo
si.GetSysInfo()
data, err := json.MarshalIndent(&si, "", " ")
if err != nil {
log.Fatal(err)
}
fmt.Println(string(data))
}
```
## Motivation
I couldn't find any self-contained library that would provide set of data/features I needed. So another sysinfo was
born.
The purpose of the library is to collect only inventory info. No metrics like CPU usage or load average will be added.
The rule of thumb is, if it's changing during the day, every day, it doesn't belong in the library.
The library should work well on any modern/supported Linux distribution. There are no plans to add support for older
unsupported Linux distributions/kernels, to keep the code clean and robust and reduce the maintenance burden.
## Requirements
Sysinfo requires:
- Linux kernel 4.2 or later
- access to /sys & /proc Linux virtual file systems
- access to various files in /etc, /var, /run FS hierarchy
- superuser privileges (to access SMBIOS/DMI table and detect RAM size and properties)
Sysinfo doesn't require ANY other external utility on the target system, which is its primary strength, IMHO.
It depends on Linux internals heavily, so there are no plans to support other operating systems.
## Installation
Just use go get.
```
go get github.com/zcalusic/sysinfo
```
There's also a very simple utility demonstrating sysinfo library capabilities. Start it (as superuser) to get pretty
formatted JSON output of all the info that sysinfo library provides. Due to its simplicity, the source code of the
utility also doubles down as an example of how to use the library.
```
go get github.com/zcalusic/sysinfo/cmd/sysinfo
```
