在构建复杂的分布式系统时,监控和追踪变得至关重要。但是,手动配置和集成各种监控工具往往是一个令人头疼的过程。OpenTelemetry旨在通过提供一套标准化的API和SDK来简化这一过程。
open-telemetry/opentelemetry
open-telemetry/opentelemetry
使用 Composer 安装
open-telemetry/opentelemetry
<pre class="brush:php;toolbar:false;">composer require open-telemetry/opentelemetry
安装完成后,你就可以开始使用 OpenTelemetry API 来收集和导出你的应用程序的遥测数据了。例如,你可以使用 OpenTelemetry API 来创建 spans (表示一个操作的执行时间) 和 metrics (表示应用程序的性能指标)。然后,你可以使用 OTLP 或 Zipkin 导出器将这些数据发送到你的监控后端。
优势:
composer require
composer.json
实际应用效果:
使用

Symfony Cache component provides an abstraction for cache management. It's designed to be flexible and extensible, supporting various cache storage adapters.
Here's how it helps solve the problem of caching in PHP applications:
Abstraction: It provides a unified interface for interacting with different cache backends (e.g., Redis, Memcached, Filesystem, Doctrine). This means you can switch between cache providers without modifying your application code.
Performance: Caching is essential for improving application performance by reducing the load on databases and other resources. Symfony Cache provides a way to store frequently accessed data in memory or on disk, so it can be retrieved quickly.
Flexibility: It supports various caching strategies, including:
PSR-16 Compatibility: It implements the PSR-16 (Simple Cache) interface, making it compatible with other caching libraries and frameworks that follow this standard.
Integration: It integrates seamlessly with other Symfony components and can be used in any PHP project.
Here's a basic example of how to use the Symfony Cache component:
<pre class="brush:php;toolbar:false;">use Symfony\Component\Cache\Adapter\FilesystemAdapter; // Create a cache adapter (in this case, using the filesystem) $cache = new FilesystemAdapter(); // Define a cache key $key = 'my_data'; // Try to retrieve the data from the cache $cachedData = $cache->getItem($key); if (!$cachedData->isHit()) { // Data is not in the cache, so fetch it from the source $data = fetchDataFromSource(); // Replace with your actual data fetching logic // Store the data in the cache $cachedData->set($data); // Set an expiration time (in seconds) $cachedData->expiresAfter(3600); // 1 hour // Save the cache item $cache->save($cachedData); } else { // Data is in the cache, so retrieve it $data = $cachedData->get(); } // Use the data echo $data;
In this example:
FilesystemAdapter
my_data
$cache->getItem($key)
!$cachedData->isHit()
$cachedData->get()
The Symfony Cache component provides a powerful and flexible way to implement caching in your PHP applications, helping you improve performance and reduce the load on your resources.
