NewRelic Instrumentation of the Elasticsearch PHP SDK

We run Elasticsearch in production, fronted by an API which abstracts away complex queries and presents our APIs which consume the data a consistent interface. It came to my attention recently that we had no visibility in NewRelic on external transaction time going to ES.

In a nutshell, the problem turned out to be that the elasticsearch-php-sdk uses RingPHP as a transport, which NewRelic doesn’t support.

I’ve written a RingPHP Guzzle Adapter which the user can pass to elasticsearch and quickly gain instrumentation.

$guzzle = new GuzzleHttp\Client();
$guzzleHandler  = new LukeWaite\RingPhpGuzzleHandler\GuzzleHandler($guzzle);

$client = Elasticsearch\ClientBuilder::create()
            ->setHandler($guzzleHandler)
            ->build();
