Overview

It's very difficult to track a request accross the system when we are working with microservices. We came out a solution for that. We generate a unique version 4 uuid for every request and every service passes this id via request header to other services. We call this correlation ID.

Packages

• proemergotech/correlate-php-laravel
  • Middleware for Laravel and Lumen frameworks.
• proemergotech/correlate-php-psr-7
  • Middleware for any PSR-7 compatible frameworks like Slim Framework.
• proemergotech/correlate-php-monolog
  • Monolog processor for correlate middlewares (you don't have to use this directly).
• proemergotech/correlate-php-guzzle
  • Guzzle middleware to add correlation id to every requests.
• proemergotech/correlate-php-core
  • Common package for correlate id middlewares to provide consistent header naming accross projects.

Installation

You should not use this directly.

By the way if you want to use it directly, you can install it via composer.

$ composer require proemergotech/correlate-php-core

Defaults

Default header name is X-Correlation-ID and default parameter name is x_correlation_id.

Usage

Generate a correlation id:

\ProEmergotech\Correlate\Correlate\Correlate::id();

Other methods:

\ProEmergotech\Correlate\Correlate::getHeaderName();
\ProEmergotech\Correlate\Correlate::getParamName();
\ProEmergotech\Correlate\Correlate::getGeneratorFunc();

// You can override defaults...
\ProEmergotech\Correlate\Correlate::setHeaderName('X-My-Correlation-ID');
\ProEmergotech\Correlate\Correlate::setParamName('my_correlation_id');
\ProEmergotech\Correlate\Correlate::setGeneratorFunc(function(){
  return uniqid();
});
