=== Enabling the Logger

Elasticsearch-PHP supports logging, but it is not enabled by default for 
performance reasons. If you wish to enable logging, you need to select a logging 
implementation, install it, then enable the logger in the Client. The 
recommended logger is https://github.com/Seldaek/monolog[Monolog], but any 
logger that implements the https://www.php-fig.org/psr/psr-3/[PSR-3] interface works.

To begin using Monolog, just require it using composer:

[source,shell]
----------------------------
composer require monolog/monolog
----------------------------

Once Monolog (or another logger) is installed, you need to create a log object 
and inject it into the client:

[source,php]
----
use Monolog\Logger;
use Monolog\Handler\StreamHandler;

$logger = new Logger('name');
$logger->pushHandler(new StreamHandler('path/to/your.log', Logger::WARNING));

$client = ClientBuilder::create()       
    ->setLogger($logger)        // Set your custom logger
    ->build();                  // Build the client object
