Introduction

ZEUS Logger provides a set of components able to record either events that occur in its core services, or messages between different processes.

By default ZEUS log entries are written to STDOUT (standard output stream) and therefore, visible as a user-friendly text in the user terminal.

Custom loggers and output streams can be specified in ZEUS configuration.

Configuration

Different output streams, as well as custom Logger adapters can be provided through a Zend Framework ServiceManager and its configuration files, like so:

<?php 
// contents of "zf3-application-directory/config/some-config.config.php" file:

return [
    'zeus_process_manager' => [
        'logger' => [
            'reporting_level' => \Zend\Log\Logger::DEBUG,
            'output' => 'php://stdout',
            'show_banner' => true,
            'logger_adapter' => 'CustomLoggerServiceName'
        ]
    ]
];

The table below describes the configuration parameters:

| Parameter | Required | Description | |--------------------|:--------:|---------------------------------------------------------------------------------------------| | reporting_level | no | Minimum severity required to log the event (see Zend\Log\Logger::*, default: DEBUG) | | output | no | Specifies where to write the logs, used only by default ZEUS logger, default: STDOUT | | show_banner | no | Controls whether default ZEUS logger should render its banner on startup or not | | logger_adapter | no | Allows to use a custom Zend\Log\LoggerInterface implementation for service logging |
