README

Unofficial PHP library for sending telemetry data to New Relic.

• ⚠️ Heavily under development, but open-sourced seeking for contributions.
• It is not an agent wrapper, it calls the New Relic Ingest APIs.

Usage

Example

Sending a Gauge metric.

use NewRelic\Adapter;
use NewRelic\Metric;

$metric_api = new Metric\API(new Adapter\Curl(getenv('NR_API_KEY')));
$metric_api->setCommonAttrs(['service.name' => 'PHP-SDK']);
$metric_api->send(new Metric\Gauge('memory.heap', 2.3));

$response = $metric_api->commit();

if ($response->isOk()) {
    echo sprintf("Request ID: %s\n", $response->getId());
} else {
    echo sprintf("Metric send error: %s\n", $response->getMessage());
}

Tips

• Make sure you are including service.instance.id when reporting your traces and/or metrics.

Why

Main reasons includes:

• Too many segfaults with the regular agent.
• Even for simple use cases the regular agent doesn't play well with Swoole. This small snippet is enough to throw a segfault:

  Co\run(static function () {
    go(static function () {
      (new Co\Http\Client('swoole.co.uk'))->get('/');
    });
  });

• There are other SDKs for other languages, this is an unofficial PHP version.
• Could be used to build a New Relic exporter for the upcoming OpenTelemetry PHP library.
