README

Build Status Latest Stable Version

The NzoElkBundle is a Symfony Bundle used to manage the logs with the ELK stack (Elasticsearch, Logstash, Kibana).

Compatible with Symfony >= 4.4

Installation

Through Composer:

$ composer require nzo/elk-bundle

Register the bundle in config/bundles.php (without Flex):

// config/bundles.php

return [
    // ...
    Nzo\ElkBundle\NzoElkBundle::class => ['all' => true],
];

Configure your application's config.yml:

# config/packages/nzo_elk.yaml
nzo_elk:
    app_name: '%env(ELK_APP_NAME)%'
    app_environment: '%env(ELK_APP_ENVIRONMENT)%'

    log_encryptor:                               # Optional
        secret_key: '%env(ELK_LOG_SECRET)%'      # Required
        fields:                                  # Required 
            - email
            - username
            - ...


# .env
ELK_APP_NAME=app
ELK_APP_ENVIRONMENT=local            

Usage

Using the JSON formatter

In the definition of the handlers, simply add the nzo.elk.monolog.formatter formatter.

Example :

api_errors:
    type: stream
    path: '%kernel.logs_dir%/%kernel.environment%.elk_api_errors.log'
    level: errors
    channels: ['api']
    formatter: nzo.elk.monolog.formatter

Encrypt Logs

This bundle offer a secure way to encrypt sensitive data sent in the logs.

To do so, You must enable and set the log_encryptor configuration and the secret_key.

In the fields configuration you must add the logs context fields that you want to be encrypted. These fields must be shared in the ELK stack in order to enable the decryption for them.

Setup:
// config/bundles.php

return [
    // ...
    Nzo\UrlEncryptorBundle\NzoUrlEncryptorBundle::class => ['all' => true],
];
Configuration:
# config/packages/nzo_elk.yaml
nzo_elk:
    # ...
    log_encryptor:
        secret_key: '%env(ELK_LOG_SECRET)%'
        fields:
            - email
            - username
            - location.address.code



# .env
ELK_LOG_SECRET=SOME_SECRET
Usage:
public function log()
{
    $context = [
        'name' => 'Wolverine',
        'username' => 'test',
        'email' => 'test@example.fr',
        'location' => [
            'address' => [
                'code' => '75000',
                'city' => 'Paris',
                'country' => 'France'
            ]
        ]
    ];

    $this->logger->error('Error', $context);
}

// The log output will be like:
[
    'name' => 'Wolverine',
    'username' => 'FbEtXzIRop0FFK31MdC+McgbWybD...',
    'email' => 'DNXDcuQDn7LbwlgLKnAgPsn...',
    'location' => [
        'address' => [
            'code' => 'FnzOIHjMZDzDmSSC...',
            'city' => 'pdjKJBDfd2Khdfkhbfk....',
            'country' => 'France'
