Publish the config

Run the following command to publish the package config file:

php artisan vendor:publish --provider="Upaid\Elk\Providers\ElkServiceProvider"

Add keys to .env

ELK_SERVICE_NAME='app name'
ELK_BANKNAME='bank name'
ELK_CHANNEL='channel for recognizing applications by logstash'

Or override config file

<?php

return [
    'logstash' => [
        'serviceName' => 'app name',
        'bankName' => 'bank name',
        'channel' => 'channel for recognizing applications by logstash',
        'showLogType' => true,
    ]
];

Changing default log fields and they order

To change default log fields or they order override fields property in config file

<?php

return [
    'logstash' => [
        'serviceName' => 'app name',
        'bankName' => 'bank name',
        'channel' => 'channel for recognizing applications by logstash',
        'fields' => [
            'timestamp',
            'severity' => 'level_name',
            'msg' => 'message',
            'span',
            'class' => 'class',
            'exception' => 'exception',
            'trace',
            'parent',
            'bank.name',
            'environment',
            'service',
            'channel',
            'context' => [
                'user.phone',
                'user.email',
                'card.id',
            ],
            'extra',
            'log_type',
        ],
        'showLogType' => true,
    ]
];

Hiding sensitive data

In order to remove sensitive data from the log file content you can add mask.fields property to the config file and specify the values of which fields should be hidden. Fields values will be replaced with mask.replacement property. It's also possible to hide values according to the patterns specified in mask.patterns. The example represents replacement of card number.

<?php

return [
    'mask' => [
        'replacement' => '[MASKED]',
        'fields' => [
            'password',
            'new_password',
            'password_confirmation',
            'card_no',
            'cvc',
        ],
        'patterns' => [
            '/^(?:4[0-9]{12}(?:[0-9]{3})?|[25][1-7][0-9]{14}|6(?:011|5[0-9][0-9])[0-9]{12}|3[47][0-9]{13}|3(?:0[0-5]|[68][0-9])[0-9]{11}|(?:2131|1800|35\d{3})\d{11})$/',
        ],
    ]
];

Add logging channel

Add elk channel to the channels array in the config/logging.php config file as follows:

'channels' => [
    'elk' => [
        'driver' => 'custom',
        'via' => \Upaid\Elk\Services\Logging\CreateCustomLogger::class,
        'log_name' => 'global'
    ],
    
    ...

In the same file set default log channel to elk:

return [
    'default' => 'elk',
    
    ...

or when you want to use stack channel (default channel is 'stack') add elk to stack channel:

'channels' => [

    ...
    
    'stack' => [
        'driver' => 'stack',
        'channels' => ['elk'],
    ],

    ...

Usage

Standard logging in Laravel (to global.json)

Log::debug('An informational message.');

Logging to custom log file name (in this case to testlog.json):

use \Upaid\Elk\Services\Logging\Logger;

$logger = new Logger('testlog');
$logger->info('Hello World!');
