将 Apache Camel 执行器指标发送到 Prometheus

2022-01-19 00:00:00 prometheus java spring-boot apache-camel

我正在尝试将 Actuator Camel 指标从 /actuator/camelroutes (路由指标，如交换/交易数量)转发/添加到 Prometheus Actuator 端点.有没有办法让我配置 Camel 以将这些指标添加到 PrometheusMeterRegistry?

I am trying to forward/add the Actuator Camel metrics from /actuator/camelroutes (route metrics like number of exchanges/transactions) to the Prometheus Actuator endpoint. Is there a way for me to configure Camel to add those metrics to the PrometheusMeterRegistry?

我已尝试添加:

camel.component.metrics.metric-registry=io.micrometer.prometheus.PrometheusMeterRegistry

根据此处的文档，在我的 application.properties 中:https://camel.apache.org/components/latest/metrics-component.html

in my application.properties according to the documentation here: https://camel.apache.org/components/latest/metrics-component.html

但 actuator/prometheus

以下是我在 Spring Boot 2.1.9 和 Apache Camel 2.24.2 中使用的依赖项:

Here are the dependencies I am using with Spring Boot 2.1.9 and Apache Camel 2.24.2:

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <dependency>
        <groupId>org.apache.camel</groupId>
            <artifactId>camel-metrics-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>io.micrometer</groupId>
            <artifactId>micrometer-registry-prometheus</artifactId>
        </dependency>

推荐答案

让 Camel Routes 指标在 /actuator/prometheus 端点中工作.

Got the Camel Routes metrics working in the /actuator/prometheus endpoint.

使用 @claus-ibsen 的评论中所述的 camel-micrometer-starter 依赖项.

Use the camel-micrometer-starter dependency as stated by @claus-ibsen 's comment.

        <dependency>
            <groupId>org.apache.camel</groupId>
            <artifactId>camel-metrics-starter</artifactId>
        </dependency>

在您的属性文件中设置以下内容:

Set the following in your properties file:

camel.component.metrics.metric-registry=prometheusMeterRegistry

然后添加设置 Camel 上下文以使用 MicrometerRouterPolicyFactory 和 MicrometerMessageHistoryFactory.下面看到的代码是配置类中的位置:

Then add set the Camel Context to use the MicrometerRouterPolicyFactory and MicrometerMessageHistoryFactory. Code seen below is places in a Configuration class:

@Configuration
public class AppConfig {

    @Bean
    public CamelContextConfiguration camelContextConfiguration() {

        return new CamelContextConfiguration() {
            @Override
            public void beforeApplicationStart(CamelContext camelContext) {
                camelContext.addRoutePolicyFactory(new MicrometerRoutePolicyFactory());
                camelContext.setMessageHistoryFactory(new MicrometerMessageHistoryFactory());
            }

            @Override
            public void afterApplicationStart(CamelContext camelContext) {

            }
        };
    }

}

您需要在路由中触发交换，以使指标显示在 /actuator/prometheus 中.

You need to trigger an exchange in a route for the metrics to appear in /actuator/prometheus.

以下是 Prometheus 可用的指标:

Here are the metrics made available to Prometheus:

  1. CamelMessageHistory_seconds_count
  2. CamelMessageHistory_seconds_max
  3. CamelRoutePolicy_seconds_max
  4. CamelRoutePolicy_seconds_count
  5. CamelRoutePolicy_seconds_sum

您可以使用 Prometheus 的 JMX Exporter jar 从 Camel 的 JMX 中获取更详细的指标.我想避免这种方法，因为这意味着对于我拥有的每个 Camel Spring Boot 应用程序将使用 2 个端口；1 个用于 JMX 指标，1 个用于执行器指标.

You can use the JMX Exporter jar for Prometheus to get the more detailed metrics from the JMX of Camel. I wanted to avoid this approach as it would mean that for each Camel Spring Boot App I have would use 2 ports; 1 for the JMX Metrics and 1 for the Actuator Metrics.
