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:

Metric	Description
Start date	ISO 8601 timestamp when the command started
End date	ISO 8601 timestamp when the command completed
Execution time	Total time in milliseconds
Memory usage	Memory consumed by the command (in MB)
Peak memory	Maximum memory used during execution (in MB)

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
