                routes: ['post_article']
                method: ~ # from all methods
                status: ~ # from all status
            get_article_not_found:

                status: [400-422, ^510, !530-550]
                level: 'error'
                options:
                    post_parameters: true # From add post parameters in response content (with DefaultFormatter)
            all_error: # All route, all method in error
                route: ~
                routes: ~
                method: ~
                status: [31*, 4*, 5*]
                level: 'critical'
    content_formatter: m6web_log_bridge.log_content_formatter # Provider service name
    ignore_headers: # key list from mask/ignore header info
        - php-auth-pw
    prefix_key: ~ # define prefix key on log context
    logger: 
        channel: my_channel_to_log # monolog channel, optional, default 'log_bridge'

Routes support multiples formats :

routes: ['my_route'] # Add only this route
routes: ['my_route', 'another_route'] # Add multiples routes
routes: ['!excluded_one', '!excluded_two'] # Add all routes except the excluded

By default, level is info

You can declare all the options you want. By default, only response_body and post_parameters is supported by the DefaultFormatter

Status support multiples formats :

status: [401] # Add status 401
status: [^456] # Add status hundred greater than 450 (456, 457, 458, ..., 499)
status: [4*] # Add status hundred (200, 400, 401, 402, ..., 499)
status: [41*] # Add status decade (410, 411, 412, ..., 419)
status: [425-440] # Add range status (425, 426, 427, ..., 440)
status: [2*, 301, !203-210] # Add status (200, 201, 202, 211, ..., 299, 301)

Instead of add can be use ! to exclude status

By default, this bundle use a builtin logger with monolog support m6web_log_bridge.logger You can override this configuration by writing your own logger who must implements Psr\Log\LoggerInterface :

# app/config.yml

m6_web_log_bridge:
    logger: 
        service: acme.logger

services:
    acme.logger:
        class: Acme\DemoBundle\Logger\logger
        arguments: ["@logger"]
        tags:
            - { name: monolog.logger, channel: log_bridge }

Acme\DemoBundle\Logger\logger must be implement Psr\Log\LoggerInterface

Define your Provider from format log content

It is advisable to extend default provider M6Web\Bundle\LogBridgeBundle\Formatter\DefaultFormatter

default definition from service provider :

    services:
        m6web_log_bridge.log_content_provider:
            class: '%m6web_log_bridge.log_content_provider.class%'
            arguments:
                - '%kernel.environment%'
                - '%m6web_log_bridge.ignore_headers%'
                - '%m6web_log_bridge.prefix_key%'
            calls:
                - [ setTokenStorage, [ '@security.token_storage' ] ]

From override :

    services:
        acme.my_log_provider:
            class: Acme\Bundle\MyBundle\Provider\LogContentProvider
            parent: m6web_log_bridge.log_content_formatter

or simply override this parameter : m6web_log_bridge.log_content_formatter.class

Logging exceptions

The bundle allow detailed logging of exceptions. This is ensured by the use of exception.log in the configuration.

# app/config.yml

m6_web_log_bridge:
    exception: 
        log: true
        request_attribute: LogBridgeException

This switch allows the bundle to register a listener which will save any received exception and passed it within the request under the defined attribute.

If you use the default formatter, change it using the configuration. The bundle provides another formatter implementation able to log exceptions.

# app/config.yml

m6_web_log_bridge:
    content_formatter: m6web_log_bridge.log_content_exception_formatter

If you prefer to use your own formatter, you will be able to read exceptions directly from the request under the attribute specified in m6_web_log_bridge.exception.request_attribute.

Tests

You can run the unit tests with the following command:

    php bin/atoum -d src/M6Web/Bundle/LogBridgeBundle/Tests/Units
