New Relic Monitoring of Swoole
==============================

This library enables monitoring of PHP applications powered by [Swoole](https://www.swoole.co.uk/) web-server via [New Relic](https://newrelic.com/) products.

**Features:**
- New Relic APM integration
- New Relic Browser integration

## Demo

## Installation

The library is to be installed via [Composer](https://getcomposer.org/) as a dependency:
```bash
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:
```php
use Upscale\Swoole\Newrelic;

$page = <<


Example page

Served by Swoole server

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:
```json
{
"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](https://github.com/killmails/polyfill-newrelic) otherwise.

## Limitations

Concurrent requests subject to [coroutine](https://www.swoole.co.uk/coroutine) multi-tasking are reported as part of the first in-flight transaction.
