Here is the script I use to get information about my linode from my linode VPS:

  }
  return $str;

  $bytes /=1024;

$year = $bwdata->year;
$month = $bwdata->month;

// $bw_max = round ( GB( floatval( $xml->bwdata->max_avail ) ), 2 ) ;
$dl = round(kb(floatval($bwdata->rx_bytes)),2);
$ul = round(kb(floatval($bwdata->tx_bytes)),2);
$total = round(kb(floatval($bwdata->total_bytes)),2);
$limit = round(kb(floatval($bwdata->max_avail)),2);
 
$precentage = round($total/$limit*100,0)."%";
 
echo ("Host: ".$xml->host->host);
echo("\n");
echo("Month: $month/$year\n");
echo("\n");
echo ("Current load: ".$xml->host->hostLoad);

echo ("CPU usage: ".$xml->cpuConsumption ."%\n");
echo ("Pending jobs: ".$xml->host->pendingJobs);
echo("\n");
echo("\n");
echo("Uploaded: ".human($ul)."\n");
echo("Downloaded: ".human($dl)."\n");
echo("Total use: ".human($total)." from ".human($limit)." allowed ($precentage)\n");
echo("\n");
 
?>

It is largely based on the PHP script you can find on Linode wiki but displays all available information and doesn’t use a temporary file saved locally.

Sample output:

$ ./lininfo 
Host: newark11.linode.com
Month: 7/2009
 
Current load: idle
CPU usage: 2.2245%
Pending jobs: 0
