log processing

[linux_terror]

Ok, I feel like this should be pretty simple but I can't see to grasp how to do it. I have a bytes_log file from apache for a virtual host. Its format is simple. Each line has a value of bytes transferred. Like this....

345
452
234
2358
234

All i need to do is create a script to read this file and add up all the values in it. Then divide it by the bandwidwidth limit. Say for example 2 gigabytes and display total bytes transferred and percentage of quota, preferably with a "progress type bar." Can anyone help me out or point me in the right direction please, I'd really appreciate it. Thanks all.

Hi..

Please be clear what kind of help you are looking...

I think you know what you need and you have quite far idea of how to do it..Do you need to learn PHP or you have something else

I was just looking to write a simple php script for it. If someone has a better idea, great. Thanks again all.

I have an idea and will work on it in the morning.

Ok, I think this will do it. This function takes 2 arguments. The first is location of log file and second is total bandwidth (IN BYTES), default is 2GB. It will print a table of used and left bandwidth, with a progress bar. I think you can take it from here and tweak it.

There is another function called convert_bytes() which just converts bytes to the closest range.

function process_bandwidth($log, $bandwidth=2147483648)
{
    // Check argument input
    if (!is_string($log)) return(false);
    if (!is_numeric($bandwidth)) return(false);

// Read the log file into an array
// Return false if it couldn't
if (($file = file($log)) === false) {
    return(false);
}

// Convert each string line into a number
foreach ($file as $key => $val) {
    settype($file[$key], 'float');
}

// Get total bytes
$bytes = array_sum($file);

// Get percent used of bandwidth
$percent = ($bytes / $bandwidth) * 100;
$percent = round($percent, 0);

// Print table for progress bar and info
print('<table cellpadding="1" cellspacing="0" width="250">' . "\r\n");
print('  <tr align="center" style="font-size:10px;">' . "\r\n");
if ($percent <= 0) {
    print('    <td colspan="2" bgcolor="#DEDEDE" style="border-left:1px solid #CC0000;">&nbsp;</td>' . "\r\n");
} elseif ($percent >= 100) {
    print('    <td colspan="2" bgcolor="#CC0000">&nbsp;</td>' . "\r\n");
} else {
    print('    <td width="' . $percent . '%" bgcolor="#CC0000">&nbsp;</td>' . "\r\n");
    print('    <td bgcolor="#DEDEDE">&nbsp;</td>' . "\r\n");
}
print('  </tr>' . "\r\n");
print('  <tr>' . "\r\n");
print('    <td colspan="2">');
print('Used: ' . convert_bytes($bytes) . ' of ' . convert_bytes($bandwidth) . ' = ' . $percent . '%');
print('</td>' . "\r\n");
print('  </tr>' . "\r\n");
print('  <tr>' . "\r\n");
print('    <td colspan="2">');
print('Left: ' . convert_bytes($bandwidth - $bytes) . ' or ' . (100 - $percent) . '%');
print('</td>' . "\r\n");
print('  </tr>' . "\r\n");
print('</table>' . "\r\n");
}
function convert_bytes($bytes) {
   if ($bytes >= 1099511627776) {
       $return = round($bytes / 1024 / 1024 / 1024 / 1024, 2);
       $suffix = 'TB';
   } elseif ($bytes >= 1073741824) {
       $return = round($bytes / 1024 / 1024 / 1024, 2);
       $suffix = 'GB';
   } elseif ($bytes >= 1048576) {

   } elseif ($bytes >= 1024) {
       $return = round($bytes / 1024, 2);
       $suffix = 'KB';
   } else {

       $suffix = 'Byte';

   if ($return == 1) {
