Detailed Description

LoggerFactory service provider that creates loggers implemented by Monolog.

Configured using an array of configuration data with the keys 'loggers', 'processors', 'handlers' and 'formatters'.

The ['loggers']['\@default'] configuration will be used to create loggers for any channel that isn't explicitly named in the 'loggers' configuration section.

Configuration will most typically be provided in the $wgMWLoggerDefaultSpi global configuration variable used by LoggerFactory to construct its default SPI provider:

$wgMWLoggerDefaultSpi = [
  'class' => \\MediaWiki\\Logger\\MonologSpi::class,
  'args' => [ [
      'loggers' => [
          '@default' => [
              'processors' => [ 'wiki', 'psr', 'pid', 'uid', 'web' ],

          ],
          'runJobs' => [

      ],
