README

This is an unofficial PHP library for OpenZipkin.

Status

Incomplete, only has one transport with zero integrations. This library contains a very minimal implementation for just sending spans to zipkin.

Getting started

The recommended way to install PHP-Zipkin is through Composer

composer require drefined/php-zipkin

Example usage

<?php
$client   = new \GuzzleHttp\Client();
$logger   = new \Drefined\Zipkin\Transport\HTTPLogger($client);
$tracer   = new \Drefined\Zipkin\Tracer($logger, 1.0, true);
$endpoint = new \Drefined\Zipkin\Core\Endpoint('127.0.0.1', 8080, 'test-trace');
$trace    = new \Drefined\Zipkin\Core\Trace($tracer, $endpoint);

$trace->createNewSpan('test-server-trace');

$trace->record(
    [Annotation::generateServerRecv()],
    [BinaryAnnotation::generateString('server.request.uri', '/server')]
);

$trace->record(
    [Annotation::generateServerSend()],
    [BinaryAnnotation::generateString('server.response', 200)]
);

Laravel integration (simple)

Add middleware and service provider in proper locations.

<?php // laravel-project/app/Http/Kernel.php

namespace App\Http;

use ...
use Drefined\Zipkin\Instrumentation\Laravel\Middleware\EnableZipkinTracing;

class Kernel extends HttpKernel
{
    ...
    protected $middleware = [
        ...
        EnableZipkinTracing::class,
    ];
    ...
}

<?php // laravel-project/config/app.php

use Drefined\Zipkin\Instrumentation\Laravel\Providers\ZipkinTracingServiceProvider;

return [
    ...
    'providers' => [
        ...
        ZipkinTracingServiceProvider::class,
    ],
    ...
];

Todo

• Add Complete Laravel integration (currently supports a simple implementation without app environment configuration)
• Add Symfony integration
• Add Redis wrapper
• Add HTTP wrapper
• Add PDO wrapper
• Add Scribe transport
• Add Kafka transport
