Feature Request: Total Cache Size on Disk Statistics

[jaswrks]

I'd like to see a graphical disk usage meter in the Dashboard (perhaps even in the admin bar too)... which shows the current total disk space consumed by Quick Cache at the present time. Or, if that's not feasible (i.e. too resource intensive) it could be updated every X minutes or so.

I think it should be a pro feature myself.

Great idea! I'll accept this and add it to my list. Thanks!

Adding this to the Future Release milestone to work on next, after the Next Release.

Two helpful methods from the WSC that might help when it comes time to implement this.

/**
 * Abbreviated byte notation for file sizes.
 *
 * @param float   $bytes File size in bytes. A (float) value.
 *    We need this converted to a (float), so it's possible to deal with numbers beyond that of an integer.
 *
 * @param integer $precision Number of decimals to use.
 *
 * @return string Byte notation.
 */
public function bytes_abbr($bytes, $precision = 2)
{
    $bytes = (float)$bytes;
    $precision = (integer)$precision;

    $precision = ($precision >= 0) ? $precision : 2;
    $units     = array('bytes', 'kbs', 'MB', 'GB', 'TB');

    $bytes = ($bytes > 0) ? $bytes : 0;
    $power = floor(($bytes ? log($bytes) : 0) / log(1024));

    $abbr_bytes = round($bytes / pow(1024, $power), $precision);
    $abbr       = $units[min($power, count($units) - 1)];

    if($abbr_bytes === (float)1 && $abbr === 'bytes')
        $abbr = 'byte'; // Quick fix here.

    else if($abbr_bytes === (float)1 && $abbr === 'kbs')
        $abbr = 'kb'; // Quick fix here.

    return $abbr_bytes.' '.$abbr;
}

/**
 * Converts an abbreviated byte notation into bytes.
 *
 * @param string $string A string value in byte notation.
 *
 * @return float A float indicating the number of bytes.
 */
public function abbr_bytes($string)
{
    $string = (string)$string;

    $notation = '/^(?P<value>[0-9\.]+)\s*(?P<modifier>bytes|byte|kbs|kb|k|mb|m|gb|g|tb|t)$/i';

    if(!preg_match($notation, $string, $_op))
        return (float)0;

    $value    = (float)$_op['value'];
    $modifier = strtolower($_op['modifier']);
    unset($_op); // Housekeeping.

    switch($modifier) // Fall through based on modifier.
    {
        case 't': // Multiplied four times.
        case 'tb':
            $value *= 1024;
        case 'g': // Multiplied three times.
        case 'gb':
            $value *= 1024;
        case 'm': // Multiple two times.
        case 'mb':
            $value *= 1024;
        case 'k': // One time only.
        case 'kb':
        case 'kbs':
            $value *= 1024;
    }
    return (float)$value;
}

Punting this to the Future Release milestone.

Don't forget to put an option to completely disable this for customers who don't want this feature in use in order to save on resource usage.

Next Pro Release Changelog:

• New Feature! Cache Statistics is a completely new ZenCache Pro feature that will help site owners better understand their WordPress site cache. An easy-to-access Cache Stats menu button in the Admin Bar is accompanied by a whole new page that shows Current Cache Totals (including total number of cache files and total size of cache on the disk), Current Disk Health (including total disk capacity and total available), Current System Health (including memory usage and load average), and two beautiful Polar Area pie charts that show you both current and historical data on Cache File Counts and Cache File Sizes with a 30-Day High, Current Total, Page Cache total, and HTML Compressor total for each chart. Props to @jaswsinc. See Issue #83.
