# Getting server info using nodejs

> Getting server information using nodejs is very easy especially using the os module. Wrote a simple script to fetch in JS.

Getting server information using nodejs is very easy especially using the os module.

Wrote a simple script to fetch **hostname, loadavg, uptime, freemem, totalmem, cpus, type, release, networkInterfaces, arch, platform, getNetworkInterfaces** from the server where the node is running.

** Below is the code to get the server info using nodejs :**

```javascript
var http = require('http');
var os = require('os');
var url = require('url');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  var call = url.parse(req.url).pathname.replace(/.*\\/|\\.[^.]*$/g, '');
  if( call === "all"){
       Object.keys(os).map(function(method) { res.write(method+":"+JSON.stringify(os[method](),2,true))+","; })
  }
  else{
      try{
          var resu = os[call]();
          res.write(JSON.stringify(resu),'utf8');
      }
      catch(e){
          res.end("Sorry, try on of : "+Object.keys(os).join(", "));
      }
  }
  res.end();
}).listen(1337, "localhost");
console.log('Server running at http://localhost:1337/');
```

After executing the above, one can just curl to get the info, say for example one needs to details of the CPUS on the server, she could **curl http://localhost:1337/cpus** and the output would be like :

```javascript
[{
    "model": "Intel(R) Core(TM)2 Quad CPU    Q6600  @ 2.40GHz",
    "speed": 2400,
    "times": {
        "user": 63400,
        "nice": 80120,
        "sys": 35010,
        "idle": 6422450,
        "irq": 0
    }
}, {
    "model": "Intel(R) Core(TM)2 Quad CPU    Q6600  @ 2.40GHz",
    "speed": 2400,
    "times": {
        "user": 72900,
        "nice": 39950,
        "sys": 29920,
        "idle": 6574560,
        "irq": 0
    }
}, {
    "model": "Intel(R) Core(TM)2 Quad CPU    Q6600  @ 2.40GHz",
    "speed": 2400,
    "times": {
        "user": 51660,
        "nice": 58230,
        "sys": 27680,
        "idle": 6518900,
        "irq": 0
    }
}, {
    "model": "Intel(R) Core(TM)2 Quad CPU    Q6600  @ 2.40GHz",
    "speed": 2400,
    "times": {
        "user": 51980,
        "nice": 57470,
        "sys": 23640,
        "idle": 6509680,
        "irq": 0
    }
}]
```

To get all details, one could just do an ajax call or a simple curl to **localhost/all** indeed 'localhost', will be the IP of your server in the code and the curl call.

This particular process as an independent unit might not be very useful, but as a helper method definitely is!
