在处理使用Symfony编写的各种微服务（并非如此）时，每次遇到导出Prometheus指标的需求时。 最初，我们只是在项目之间复制了相同的代码，但是当其中有三个以上时，我以为我不能继续这样（我不会费心解释为什么这样做不方便；我想每个人都可以自己理解）。
决定将整个经济分成一个单独的捆绑包：
ArtprimaPrometheusMetricsBundle 。
为所有应用程序选择通用指标，我着手编写捆绑软件。 该
客户端被选为
Jimdo / prometheus_client_php客户端 ，它允许您用作统计存储：Redis（通过ext-redis），APCu（通过ext-apcu）和InMemory（在PHP内存中，仅在进程生命周期内）。 我将立即保留在实践中仅测试APCu（我需要具有每个实例的统计信息，而在Redis中将有共享的统计信息，除非将Redis部署到每个实例中）。 通常，InMemory，恕我直言，只能用于测试。
Jimdo / prometheus_client_php立即出现问题-很长时间没有发布，并且所需的功能（APCu）也无法作为发布使用。 在这方面，我做
了client的fork ，不同之处仅在于它具有用于生成发行版的正确标签。
我遇到的第二个问题是Symfony的食谱。 您甚至不必插手正式的仓库，社区对拉取请求的请求将花费很长时间（目前该捆绑包已使用了将近一个月，而
PR配方仍在考虑中）。 因此，在安装过程中，您需要手动进行必要的设置。 幸运的是，它们并不多。
实际上，您需要配置主要配置：
#config/packages/prometheus-metrics.yaml artprima_prometheus_metrics: # namespace prometheus namespace: myapp # type: in_memory # : in_memory, apcu, redis # , ignored_routes: [some_route_name, another_route_name] # "redis" ( ) redis: host: 127.0.0.1 port: 6379 timeout: 0.1 read_timeout: 10 persistent_connections: false password: ~
然后，您需要导出路线：
或者，您可以手动配置路由：
app_metrics: path: /mypath/mymetrics controller: Artprima\PrometheusMetricsBundle\Controller\MetricsController::prometheus
做完了 因此，您的指标将在http [s]上提供：// your_host / metrics / prometheus（如果您未更改路径）。 一段时间后，您会得到如下信息：

自然，很快可能没有足够的基本度量标准，因此您总是有机会编写自己的度量标准生成器（除了现有的度量标准生成器）并按如下所示导出它：
# config/services.yaml App\Metrics\MyMetricsGenerator: tags: - { name: prometheus_metrics_bundle.metrics_generator }
同时，您的生成器应实现
Artprima\PrometheusMetricsBundle\Metrics\MetricsGeneratorInterface 。 您可以在
Artprima\PrometheusMetricsBundle\Metrics\AppMetrics查看生成器的外观。 您在这里需要知道的主要事情
collectRequest在
kernel.request事件上
collectResponse方法，而在
collectResponse事件上
collectResponse方法。
我本质上接受批评。 都以技巧和PR的形式出现：-)
PS警告我们发明了自行车的评论：是的，我知道还有其他选择。 而且，很可能它们肯定会更好。 特别是其中之一是
TweedeGolfPrometheusBundle 。 不幸的是，我不记得为什么我们没有选择这种解决方案，但是六个多月前，我们尝试了并拒绝了。 无论如何，我相信选择总是一件好事，这就是为什么我们的捆绑软件在OpenSource中发布的原因。
