1[[enabling_logger]] 2=== Enabling the Logger 3 4Elasticsearch-PHP supports logging, but it is not enabled by default for 5performance reasons. If you wish to enable logging, you need to select a logging 6implementation, install it, then enable the logger in the Client. The 7recommended logger is https://github.com/Seldaek/monolog[Monolog], but any 8logger that implements the `PSR/Log` interface works. 9 10You might have noticed that Monolog was suggested during installation. To begin 11using Monolog, add it to your `composer.json`: 12 13[source,json] 14---------------------------- 15{ 16 "require": { 17 ... 18 "elasticsearch/elasticsearch" : "~5.0", 19 "monolog/monolog": "~1.0" 20 } 21} 22---------------------------- 23 24And then update your Composer installation: 25 26[source,shell] 27---------------------------- 28php composer.phar update 29---------------------------- 30 31Once Monolog (or another logger) is installed, you need to create a log object 32and inject it into the client: 33 34[source,php] 35---- 36use Monolog\Logger; 37use Monolog\Handler\StreamHandler; 38 39$logger = new Logger('name'); 40$logger->pushHandler(new StreamHandler('path/to/your.log', Logger::WARNING)); 41 42$client = ClientBuilder::create() // Instantiate a new ClientBuilder 43 ->setLogger($logger) // Set your custom logger 44 ->build(); // Build the client object 45----
