README

Logging gives you a simple abstraction compatible with PSR-3 logger interface that you can connect to a different backend to customize your logging needs

Logging provides a thin PSR-7 interface abstraction to connect any logging facility behind it.

Installation

Require the library as usual:

composer require "pluggit/logging"

Monolog

This library provides Monolog as its main logging backend. You will need to install the library manually:

composer require monolog/monolog ^1.2

To create factory, set default channel name as first parameter and Formatter as second one.

<?php
use Cmp\Logging\Monolog\LoggingFactory;
use Monolog\Formatter\JsonFormatter;
$logger = new LoggingFactory('yoursite', 'error_channel', new JsonFormatter(true));

Handlers

The library provides a factory to ease the addition of some handlers to the logger objects,

Built in handlers

• RotatingFileHandler
  This handler will write the log messages to a file, rotating the name depending on the given date format

<?php
use Cmp\Logging\Monolog\LoggingFactory;
use Monolog\Formatter\JsonFormatter;
use Monolog\Logger;

$logger = new LoggingFactory('yoursite', 'error_channel', new JsonFormatter(true));

// addRotatingFileHandlerBuilder(directory path, date format, max files number, file name, file name format, level)
$logger->addRotatingFileHandlerBuilder('directory/path','Y-m-d', 14, '{channel}.log', '{date}_{filename}', Logger::ERROR);

• SyslogUdpHandler
  This handler will send a UDP packet with the log message, useful to send messages to 3rd party log platforms or storage servers (like ElasticSearch)

<?php
use Cmp\Logging\Monolog\LoggingFactory;
use Monolog\Formatter\JsonFormatter;

$logger = new LoggingFactory('yoursite', 'error_channel', new JsonFormatter(true));

//addSyslogUdpHandlerBuilder(syslog UDP Host, syslog UDP Port, level)
$logger->addSyslogUdpHandlerBuilder('12.34.56.78', '90', Logger::ERROR);

Adding custom handler

To add custom handler you should write handler builder implementing HandlerBuilderInterface:

<?php
namespace Cmp\Logging\Monolog\Handler;

use Monolog\Formatter\FormatterInterface;
use Monolog\Handler\AbstractHandler;

interface HandlerBuilderInterface
{
    /**
     * @param string             $channelName
     * @param array              $processors
     * @param FormatterInterface $formatter
     *
     * @return AbstractHandler
     */
    public function build($channelName, FormatterInterface $formatter, $processors = []);
}

The handler builder should be added using addHandlerBuilder method:

<?php
use Cmp\Logging\Monolog\LoggingFactory;
use Monolog\Formatter\JsonFormatter;
use Customer\Namespace\CustomHandlerBuilder;

$logger = new LoggingFactory('yoursite', 'error_channel', new JsonFormatter(true));
$handlerBuilder = new CustomHandlerBuilder($param1, $param2);
$logger->addHandlerBuilder($handlerBuilder);

Error handler

To add default error handler use addErrorHandlerBuilder method.

<?php
use Cmp\Logging\Monolog\LoggingFactory;
use Monolog\Formatter\JsonFormatter;
use Customer\Namespace\CustomHandlerBuilder;

$logger = new LoggingFactory('yoursite', 'error_channel', new JsonFormatter(true));
$handlerBuilder = new CustomHandlerBuilder($param1, $param2);
$logger->addErrorHandlerBuilder($handlerBuilder);

Processors

<?php
use Cmp\Logging\Monolog\LoggingFactory;
use Monolog\Formatter\JsonFormatter;
use Customer\Namespace\CustomHandlerBuilder;
use Monolog\Logger\GitProcessor;

$logger = new LoggingFactory('yoursite', 'error_channel', new JsonFormatter(true));
//addProcessor(callable $processor)
$logger->addProcessor(new GitProcessor(Logger:DEBUG));
