README

This library enables monitoring of PHP applications powered by Swoole web-server via New Relic products.

Features:

New Relic APM integration
New Relic Browser integration

Demo

Installation

The library is to be installed via Composer as a dependency:

composer require upscale/swoole-newrelic

Usage

Production

Monitoring of requests from start to finish can be activated by adding a few lines of code to the server entry point. The monitoring instrumentation is by design completely transparent to an application running on the server.

Install the monitoring instrumentation for all requests:

use Upscale\Swoole\Newrelic;

$page = <<<HTML
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Example page</title>
</head>
<body>
    Served by Swoole server
</body>
</html>

HTML;

$server = new \Swoole\Http\Server('127.0.0.1', 8080);
$server->on('request', function ($request, $response) use ($page) {
    // PHP processing within request boundary...
    usleep(1000 * rand(100, 300));
    
    // Send response
    $response->end($page);
    
    // PHP processing outside of request boundary...
    usleep(1000 * rand(50, 150));
});

// Real user monitoring (RUM)
$rum = new Newrelic\Browser(new Newrelic\Browser\TransactionFactory());
$rum->instrument($server);

// Application performnce monitoring (APM)
$apm = new Newrelic\Apm(new Newrelic\Apm\TransactionFactory());
$apm->instrument($server);

unset($rum, $apm);

$server->start();

APM can be standalone or used in conjunction with the real user monitoring. RUM must be instrumented first.

Browser instrumentation is applied to non-AJAX requests having text/html response MIME type (the default).

Development

Having to install the New Relic PHP extension locally may be inconvenient and outright undesirable for developers. The workaround is to replace the New Relic reporting functionality with the "stub" implementation doing nothing:

{
    "require": {
        "upscale/swoole-newrelic": "^1.0",
        "killmails/polyfill-newrelic": "^1.0"
    },
    "replace": {
        "ext-newrelic": "*"
    }
}

The PHP extension is used when installed and substituted with the polyfill otherwise.

Limitations

Concurrent requests subject to coroutine multi-tasking are reported as part of the first in-flight transaction.
