README

Statistics that help you improve application performance.

Telltale analyses current execution and provides information about potential bottlenecks in your application. Analyzes are executed by agents. Output reports are automatically sent to console of your browser. Available agents:

• Memory Peak;
• Critical Path;
• Slowest Calls;
• Memory Usage Calls.

Usage

<?php

use Telltale\Telltale;
use Telltale\Agent\MemoryPeakAgent;
use Telltale\Agent\CriticalPathAgent;
use Telltale\Agent\SlowestCallsAgent;
use Telltale\Agent\MemoryUsageCallsAgent;

// create an analyser
$telltale = new Telltale();
$telltale->pushAgent(new MemoryPeakAgent());
$telltale->pushAgent(new CriticalPathAgent());
$telltale->pushAgent(new SlowestCallsAgent());
$telltale->pushAgent(new MemoryUsageCallsAgent());

// start watching
$telltale->start();

Then your browser displays informations like this...

Analysing a code snippet...

<?php
// ignored
$telltale->start();
// analysed
$telltale->stop();
// ignored
