Console Metrics Bundle

A Symfony bundle that adds detailed performance metrics to your console commands.

Features

• 📊 Displays execution time, memory usage, and timestamps for any console command
• ⚡ Zero configuration required - works out of the box
• 🎯 Opt-in per command execution with a simple flag
• 🔧 Fully customizable option name and shortcut
• 🚀 Compatible with Symfony 7.4, and 8.0+

Prerequisites

• PHP: >= 8.2
• Symfony: 7.4.x, or 8.0+

Installation

Step 1: Install the bundle

composer require ekino/console-metrics-bundle

Step 2: Register the bundle (if not using Symfony Flex)

If your Symfony application doesn't use Symfony Flex, manually add the bundle to your config/bundles.php file:

<?php

return [
    // ...other bundles...
    Ekino\ConsoleMetricsBundle\ConsoleMetricsBundle::class => ['all' => true],
];

How it works

Once installed, the bundle automatically registers event listeners that:

• AddMetricsOptionListener: Adds a --metrics option to all console commands
• ConsoleBeforeListener: Starts tracking metrics when the option is enabled
• ConsoleAfterListener: Displays the collected metrics after command execution

Usage

Basic usage

Simply add the --metrics option (or its shortcut -m) to any console command:

php bin/console your:command --metrics

Collected metrics

The bundle displays the following information:

Configuration

You can customize the option name and shortcut by creating a configuration file at config/packages/console_metrics.yaml:

# config/packages/console_metrics.yaml
console_metrics:
    metrics_option_name: 'perf'        # Default: 'metrics'
    metrics_option_shortcut: 'p'       # Default: 'm'

With this configuration, you would use:

php bin/console your:command --perf
# or
php bin/console your:command -p

Example output

Running a command with the metrics option enabled:

$ php bin/console app:my-command --metrics
