Unofficial PHP library for sending telemetry data to New Relic.

Status API Description
Trace API Used to send distributed tracing data to New Relic (New Relic's format).
Metric API Used to send metric data to New Relic.
Event API Is one way to report custom events to New Relic.
- Log API Not planned.
  • ⚠️ Heavily under development, but open-sourced seeking for contributions.
  • It is not an agent wrapper, it calls the New Relic Ingest APIs.



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());

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.
