Enhanced Cloud Logging Formatter v3.x

Note v3.x version is only compatible with Monolog 3.x, please use v2.x if you use Monolog 2.x.

The Enhanced Cloud Logging Formatter is a custom formatter for Monolog that replaces the default GoogleCloudLoggingFormatter provided by Monolog. This formatter is designed to be used when you want to send logs from your PHP application to Google Cloud Logging.

Features

Error Reporting: The GoogleCloudLoggingFormatter enables error reporting, allowing you to control the reporting of error events to Google Cloud Platform (GCP). The errorReportingLevel parameter can be modified to specify the minimum log level that triggers error reporting.
Complete Log Metadata: This formatter completes log metadata, providing additional context information before sending logs to GCP. This ensures that logs include comprehensive details, making it easier to analyze and debug issues. Additional metadata contains:
- Unique RequestId to easily search all the logs for a single HTTP request
- Exhaustive HTTP info for each log entries, such as request Url, referer, remote IP and User Agent
- For CLI commands, script command and script filename called
- When an error is thrown, add information about error context (report location, stack trace, exception message, service name and version number if they are provided)

Installation

You can install the Enhanced Cloud Logging Formatter via Composer:

composer require vimar/enhanced-cloud-logging-formatter

Basic Usage

To use the GoogleCloudLoggingFormatter, you need to configure Monolog in your application.

<?php

require_once 'vendor/autoload.php';

use Monolog\Logger;
use Monolog\Handler\StreamHandler;
use Vimar\EnhancedCloudLoggingFormatter\Formatter\GoogleCloudLoggingFormatter;

// Create a logger
$log = new Logger('my_logger');

// Create a handler with GoogleCloudLoggingFormatter
$handler = new StreamHandler('php://stdout');
$handler->setFormatter(new GoogleCloudLoggingFormatter());

// Add the handler to the logger
$log->pushHandler($handler);

// Example logs
$log->info('This is an informational message.');
$log->error('An error occurred!');

In this example, logs are sent to the standard output (php://stdout) using a StreamHandler with the GoogleCloudLoggingFormatter. Adjust the handler configuration based on your specific logging needs.

The GoogleCloudLoggingFormatter replaces the default Google Cloud Logging formatter from Monolog and supports the following configuration option:

errorReportingLevel - The minimum log level that triggers error reporting.
