id="introduction"><a href="#introduction">Introduction</a></h2> <p>To help you learn more about what's happening within your application, Laravel provides robust logging services that allow you to log messages to files, the system error log, and even to Slack to notify your entire team.</p> <p>Laravel logging is based on "channels". Each channel represents a specific way of writing log information. For example, the <code>single</code> channel writes log files to a single log file, while the <code>slack</code> channel sends log messages to Slack. Log messages may be written to multiple channels based on their severity.</p> <p>Under the hood, Laravel utilizes the <a href="https://github.com/Seldaek/monolog">Monolog</a> library, which provides support for a variety of powerful log handlers. Laravel makes it a cinch to configure these handlers, allowing you to mix and match them to customize your application's log handling.</p> <h2 id="configuration"><a href="#configuration">Configuration</a></h2> <p>All of the configuration options that control your application's logging behavior are housed in the <code>config/logging.php</code> configuration file. This file allows you to configure your application's log channels, so be sure to review each of the available channels and their options. We'll review a few common options below.</p> <p>By default, Laravel will use the <code>stack</code> channel when logging messages. The <code>stack</code> channel is used to aggregate multiple log channels into a single channel. For more information on building stacks, check out the <a href="#building-log-stacks">documentation below</a>.</p> <h3 id="available-channel-drivers"><a href="#available-channel-drivers">Available Channel Drivers</a></h3> <p>Each log channel is powered by a "driver". The driver determines how and where the log message is actually recorded. The following log channel drivers are available in every Laravel application. An entry for most of these drivers is already present in your application's <code>config/logging.php</code> configuration file, so be sure to review this file to become familiar with its contents:</p> <div class="overflow-auto"> <table> <thead> <tr> <th>Name</th> <th>Description</th> </tr> </thead> <tbody> <tr> <td><code>custom</code></td> <td>A driver that calls a specified factory to create a channel.</td> </tr> <tr> <td><code>daily</code></td> <td>A <code>RotatingFileHandler</code> based Monolog driver which rotates daily.</td> </tr> <tr> <td><code>errorlog</code></td> <td>An <code>ErrorLogHandler</code> based Monolog driver.</td> </tr> <tr> <td><code>monolog</code></td> <td>A Monolog factory driver that may use any supported Monolog handler.</td> </tr> <tr> <td><code>papertrail</code></td> <td>A <code>SyslogUdpHandler</code> based Monolog driver.</td> </tr> <tr> <td><code>single</code></td> <td>A single file or path based logger channel (<code>StreamHandler</code>).</td> </tr> <tr> <td><code>slack</code></td> <td>A <code>SlackWebhookHandler</code> based Monolog driver.</td> </tr> <tr> <td><code>stack</code></td> <td>A wrapper to facilitate creating "multi-channel" channels.</td> </tr> <tr> <td><code>syslog</code></td> <td>A <code>SyslogHandler</code> based Monolog driver.</td> </tr> </tbody> </table> </div> <div class="mb-10 max-w-2xl mx-auto px-4 py-8 shadow-lg lg:flex lg:items-center callout"> <div class="w-20 h-20 mb-6 flex items-center justify-center shrink-0 lg:mb-0 bg-purple-600"> <div class="opacity-75"><svg width="28" height="40" viewBox="0 0 28 40" xmlns="http://www.w3.org/2000/svg"><title>lightbulb</title><path d="M12 28h4v-8h-4v8zM8 40h12v-8H8v8zm13.98-14.52c-1.001.705-1.661 1.545-1.98 2.52H8c-.416-.959-1.076-1.799-1.98-2.52A13.99 13.99 0 0 1 0 14C0 6.272 6.272 0 14 0s14 6.272 14 14a13.99 13.99 0 0 1-6.02 11.48z" fill="#FFF" fill-rule="nonzero"/></svg></div> </div> <p class="mb-0 lg:ml-6 callout"> Check out the documentation on <a href="#monolog-channel-customization">advanced channel customization</a> to learn more about the <code>monolog</code> and <code>custom</code> drivers.</p> </div> <h4 id="configuring-the-channel-name"><a href="#configuring-the-channel-name">Configuring the Channel Name</a></h4> <p>By default, Monolog is instantiated with a "channel name" that matches the current environment, such as <code>production</code> or <code>local</code>.

First, notice our <code>stack</code> channel aggregates two other channels via its <code>channels</code> option: <code>syslog</code> and <code>slack</code>. So, when logging messages, both of these channels will have the opportunity to log the message. However, as we will see below, whether these channels actually log the message may be determined by the message's severity / "level".</p> <h4 id="log-levels"><a href="#log-levels">Log Levels</a></h4> <p>Take note of the <code>level</code> configuration option present on the <code>syslog</code> and <code>slack</code> channel configurations in the example above. This option determines the minimum "level" a message must be in order to be logged by the channel. Monolog, which powers Laravel's logging services, offers all of the log levels defined in the <a href="https://tools.ietf.org/html/rfc5424">RFC 5424 specification</a>. In descending order of severity, these log levels are: <strong>emergency</strong>, <strong>alert</strong>, <strong>critical</strong>, <strong>error</strong>, <strong>warning</strong>, <strong>notice</strong>, <strong>info</strong>, and <strong>debug</strong>.</p> <p>So, imagine we log a message using the <code>debug</code> method:</p> <pre><code data-theme="olaolu-palenight" data-lang="php" class='torchlight' style='background-color: #292D3E; --theme-selection-background: #7580B850;'><div class='line'><span style="color: #FFCB8B;">Log</span><span style="color: #89DDFF;">::</span><span style="color: #82AAFF;">debug</span><span style="color: #BFC7D5;">(</span><span style="color: #D9F5DD;">'</span><span style="color: #C3E88D;">An informational message.</span><span style="color: #D9F5DD;">'</span><span style="color: #BFC7D5;">);</span></div></code></pre> <p>Given our configuration, the <code>syslog</code> channel will write the message to the system log; however, since the error message is not <code>critical</code> or above, it will not be sent to Slack. However, if we log an <code>emergency</code> message, it will be sent to both the system log and Slack since the <code>emergency</code> level is above our minimum level threshold for both channels:</p> <pre><code data-theme="olaolu-palenight" data-lang="php" class='torchlight' style='background-color: #292D3E; --theme-selection-background: #7580B850;'><div class='line'><span style="color: #FFCB8B;">Log</span><span style="color: #89DDFF;">::</span><span style="color: #82AAFF;">emergency</span><span style="color: #BFC7D5;">(</span><span style="color: #D9F5DD;">'</span><span style="color: #C3E88D;">The system is down!</span><span style="color: #D9F5DD;">'</span><span style="color: #BFC7D5;">);</span></div></code></pre> <h2 id="writing-log-messages"><a href="#writing-log-messages">Writing Log Messages</a></h2> <p>You may write information to the logs using the <code>Log</code> <a href="/docs/11.x/facades">facade</a>.

Unlike the standard <code>tail</code> command, Pail is designed to work with any log driver, including Sentry or Flare. In addition, Pail provides a set of useful filters to help you quickly find what you're looking for.</p> <img src="https://laravel.com/img/docs/pail-example.png"> <h3 id="pail-installation"><a href="#pail-installation">Installation</a></h3> <div class="mb-10 max-w-2xl mx-auto px-4 py-8 shadow-lg lg:flex lg:items-center callout"> <div class="w-20 h-20 mb-6 flex items-center justify-center shrink-0 lg:mb-0 bg-red-600"> <div class="opacity-75"><svg width="6" height="35" viewBox="0 0 6 35" xmlns="http://www.w3.org/2000/svg"><title>exclamation</title><path d="M0 29h6v6H0v-6zM0 0h6v24H0V0z" fill="#FFF" fill-rule="nonzero"/></svg> </div> </div> <p class="mb-0 lg:ml-6 callout"> Laravel Pail requires <a href="https://php.net/releases/">PHP 8.2+</a> and the <a href="https://www.php.net/manual/en/book.pcntl.php">PCNTL</a> extension.</p> </div> <p>To get started, install Pail into your project using the Composer package manager:</p> <div class="code-container"> <pre><code data-theme="olaolu-palenight" data-lang="bash" class='torchlight' style='background-color: #292D3E;
