Laravel Contextify

Contextual logging in Laravel

This package allows you to write log messages fitted with the execution context, including the class, PID, UID (and more), directly from your application PHP classes. It provides a PHP trait that allows you to achieve this. Additionally, it provides various enhancements to the native Laravel Logging functionality.

Adding execution context to logs very helpful when your application has grown in size and complexity, and you begin to facing a large number of logs originating from various parts of the application, including multiple processes such as queue workers and daemons.

By examining the class of a log record, you can easily determine its source. It also groups together all log records associated with that class.

The PID groups all log records related to a specific process, such as a queue worker or daemon.

The UID combines all log records associated with the processing of a single user request or, for instance, the execution of a single console command.

The MEM indicates the amount of memory allocated from system (including unused pages) to PHP at the time of adding a log record.

Log records will be looks like this:

[2023-03-07 19:26:26] local.NOTICE: [App\Services\OrderService] [PID:56] [UID:640765b20b1c0] [MEM:31457280] Order was created

In addition, this package allows to:

• Send log records as notifications via mail, telegram and other channels
• Send exception notification via mail, telegram and other channels
• Track Console Command execution
• Capture native Console Command output and write it to logs
• Handle shutdown signals by Console Command

Installation

composer require faustoff/laravel-contextify:^2.0

Publishing config file

Optionally, you can publish the health config file with this command:

php artisan vendor:publish --tag="contextify-config"

Usage

Contextual Logging

Suppose you have kind of OrderService in your application.

To add contextual logging to OrderService use Faustoff\Contextify\Loggable trait and methods like $this->logInfo() which trait provides:

Log:

Parent Context

If you have multiple levels of logging context you can pass "parent" loggable to "child" by using Faustoff\Loggable\HasLog trait.

Suppose you have "parent" logging context OrderController and "child" OrderService and you want to pass OrderController logging context to OrderService.

Log:

Notifications

Out of the box, the notification can be sent via:

• mail
• Telegram

If you want to send Email notifications you should configure CONTEXTIFY_MAIL_ADDRESSES environment variable. You can pass multiple addresses by separating them with commas like this:

If you want to send Telegram notifications you should install and configure laravel-notification-channels/telegram package. Then you should set CONTEXTIFY_TELEGRAM_CHAT_ID environment variable with retrieved Telegram Chat ID.

Want more notification channels? You are welcome to Laravel Notifications Channels.

Also, you can override which queue (default queue by default) will be used to send a specific notification through a specific channel. This will be done in contextify config by key notifications.list like this:

You can completely disable notifications by CONTEXTIFY_NOTIFICATIONS_ENABLED environment variable.

Log Notifications

To send log notification you should set third parameter of logInfo()-like methods to true:

Exception Notifications

You will receive notifications about any unhandled reportable exceptions.

To turn off, set empty value to notifications.exception_handler.reportable key of contextify configuration file.

Console Commands

If you wants to add contextual logging in to console commands, you can use Faustoff\Contextify\Console\Loggable trait. It extends common Faustoff\Contextify\Loggable by writing logs to console output (terminal).

Log:

Terminal output:

Console Command Tracking

Also, you can track console command execution by using Faustoff\Contextify\Console\Trackable trait. It adds additional debug log entries when console commands starts and finish with execution time and peak memory usage.

Log:

Terminal output:

Console Command Output Capturing

Also, you can capture native Laravel console command output, produced by info()-like methods, and store it to logs by using Faustoff\Contextify\Console\Outputable trait:

Log:

Terminal output:

Console Command Handling Shutdown Signals

You can handle shutdown signals (SIGQUIT, SIGINT and SIGTERM by default) from Console Command to graceful shutdown command execution by using Faustoff\Contextify\Console\Terminatable trait and Symfony\Component\Console\Command\SignalableCommandInterface interface together:
