You can parse your site's apache access log to figure out the total bandwidth. Here's a loose pseudo-php example (the actual implementation will depend on your log format):

<?php
$logfile = '/var/log/apache/httpd-access.log';
$startDate = '2010-10-01';
$endDate = '2010-10-31';

$fh = fopen($logfile, 'r');

if (!$fh) die('Couldn\'t open log file.');

$totalBytes = 0;

// let's pretend the log is a csv file because i'm lazy at parsing
while (($info = fgetcsv($fh, 0, ' ', '"')) !== false) {
  // get the date of the log entry
  $date = $info[3];
  // check if the date is within our month of interest
  if ($date > $startDate && $date < $endDate) {
    // get the number of bytes sent in the request
    $totalBytes += $info[7];
  }
}

fclose($fh);

echo 'Total bytes used: ' . $totalBytes;

Also, this script is likely to be very slow depending on size of your logs, so you should considering caching the result for later use instead of running it repeatedly.

your best bet is to parse number of packets that passed ethX inteface command that keeps track of bytes passed is /sbin/ifconfig Keep in mind that counters are reset if you reboot your linux box

eth0      
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:32363649 errors:0 dropped:0 overruns:0 frame:0
          TX packets:35133219 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:2813232645 (2.6 GiB)  TX bytes:1696525681 (1.5 GiB)
          Interrupt:16 Memory:f4000000-f4012700
