Solve the dilemma of microservice log management: Use mkrutikov/microservice_logging

Log management has always been a challenge in microservice architecture. As system complexity increases, it becomes crucial to achieve consistent logging and tracing between different services. During the project development process, we encountered the following problems:

1. Log scatter : Each microservice has its own log, which is difficult to centrally manage and view.
2. Tracking Difficulty : The inability to effectively track requests flow between different services, resulting in complex debugging and problem location.
3. Performance Impact : Too much logging may affect system performance.

To solve these problems, we decided to try using mkrutikov/microservice_logging library. This library is specially designed for microservice log management, and is very convenient to install through Composer:

 <code>composer require mkrutikov/microservice_logging:~1.0</code>

mkrutikov/microservice_logging provides a series of functions to help us solve the above problems:

• RabbitMQ Integration : By sending logs to RabbitMQ, we are able to centrally manage and view logs from different microservices. This makes unified log management easier.

  For example, in client code, we can configure it like this:

   <code class="language-php">$connection = new AMQPStreamConnection(HOST, PORT, USER, PASS, VHOST); $amqpHandlerFactory = new RabbitLogHandlerFactory($connection); $amqpHandler = $amqpHandlerFactory->createHandler('logging', 'log'); $logger = new Logger('logger_name'); $logger->pushHandler($amqpHandler); // 现在可以记录日志消息$logContext = []; $logContext['guid'] = '555'; $messageBody = 'Текст сообщения'; $logger->debug($messageBody, $logContext);</code>

• GUID Generation and Passing : Through GuidGenerator class, we can generate and pass a unique GUID to track the flow of requests between different services.

  Usage example:

   <code class="language-php">$guidGenerator = new GuidGenerator($_SERVER); $guid = $guidGenerator->getGuid();</code>

• Microservice call : The MicroserviceClient class is a Guzzle wrapper that can pass the GUID to the request's header to ensure the traceability of the request.

  Usage example:

   <code class="language-php">$microserviceClient = new MicroserviceClient($guid); $microserviceResponse = $microserviceClient->request('GET', 'http://city_service.m.krutikov.docker:8080/index.php'); echo $microserviceResponse->getBody();</code>

With this library, our log management becomes more efficient and centralized. With RabbitMQ, we can easily view and manage logs for all microservices. The use of GUID makes request tracking simple, greatly improving debugging efficiency. At the same time, the performance of this library is also excellent and has not had a significant impact on system performance.

If you are also having a headache about log management for microservices, you might as well try mkrutikov/microservice_logging. You can learn more about Composer through the following address: Learning Address .

In general, mkrutikov/microservice_logging not only solves our practical problems, but also provides us with an efficient microservice log management solution, which greatly improves the team's work efficiency and system maintainability.
