Methods

public static application( ) (defined in Kohana_Profiler)

Gets the total application run time and memory usage. Caches the result so that it can be compared between requests.

list($time, $memory) = Profiler::application();

Return Values

array - Execution time, memory

Source Code

public static function application()
{
	// Load the stats from cache, which is valid for 1 day
	$stats = Kohana::cache('profiler_application_stats', NULL, 3600 * 24);

	// Get the application run time
	$time = microtime(TRUE) - KOHANA_START_TIME;

	// Get the total memory usage

	// Determine the averages
	$stats['average'] = array(

	// Cache the new stats

public static stop( string $token ) (defined in Kohana_Profiler)

Stops a benchmark.

Profiler::stop($token);

Parameters

string $token required - $token

Return Values

void

Source Code

public static function stop($token)
{
	// Stop the benchmark
	Profiler::$_marks[$token]['stop_time']   = microtime(TRUE);
	Profiler::$_marks[$token]['stop_memory'] = memory_get_usage();
}

public static total( string $token ) (defined in Kohana_Profiler)

Gets the total execution time and memory usage of a benchmark as a list.

list($time, $memory) = Profiler::total($token);

Parameters

string $token required - $token

Return Values

array - Execution time, memory

Source Code

public static function total($token)
{
	// Import the benchmark data
	$mark = Profiler::$_marks[$token];

	if ($mark['stop_time'] === FALSE)
	{
		// The benchmark has not been stopped yet
		$mark['stop_time']   = microtime(TRUE);
		$mark['stop_memory'] = memory_get_usage();
	}

	return array
	(
		// Total time in seconds
		$mark['stop_time'] - $mark['start_time'],

		// Amount of memory in bytes
		$mark['stop_memory'] - $mark['start_memory'],
	);
