将Apache Camel执行器指标发送给Prometheus [英] Send Apache Camel Actuator Metrics to Prometheus
问题描述
我正在尝试将来自/actuator/camelroutes
的执行器骆驼度量(路由度量,如交换/交易次数)转发/添加到Prometheus执行器端点.我可以配置骆驼以将这些指标添加到PrometheusMeterRegistry吗?
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?
我尝试添加:
camel.component.metrics.metric-registry=io.micrometer.prometheus.PrometheusMeterRegistry
根据此处的文档在 application.properties
中
这是我在 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
使用在/actuator/prometheus
端点中工作的骆驼路线度量标准.
Got the Camel Routes metrics working in the /actuator/prometheus
endpoint.
使用@ claus-ibsen的评论所述的 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
然后添加设置骆驼上下文以使用MicrometerRouterPolicyFactory和MicrometerMessageHistoryFactory.下面显示的代码是Configuration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) {
}
};
}
}
您需要触发路由交换,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
.
以下是可供普罗米修斯使用的指标:
Here are the metrics made available to Prometheus:
- CamelMessageHistory_seconds_count
- CamelMessageHistory_seconds_max
- CamelRoutePolicy_seconds_max
- CamelRoutePolicy_seconds_count
- CamelRoutePolicy_seconds_sum
您可以使用Prometheus的JMX导出器jar从Camel的JMX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;JMX指标为1,执行器指标为1.
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.
