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 Monolog, but any logger that implements the PSR-3 interface works.
To begin using Monolog, just require it using composer:
composer require monolog/monolog
Once Monolog (or another logger) is installed, you need to create a log object and inject it into the client:
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
