在Spring Boot Camel应用程序公开的Micrometer/Prometheus信息中包含额外的JMX度量

Question

我已经用Camel 3.9配置了一个Spring Boot2应用程序，以便通过Actuator/Prometheusendpoint使用Micrometer公开度量标准，并正确返回一些Camel度量标准：

# HELP CamelExchangesFailed_total  
# TYPE CamelExchangesFailed_total counter
CamelExchangesFailed_total{camelContext="camel-1",routeId="route3",serviceName="MicrometerRoutePolicyService",} 0.0
CamelExchangesFailed_total{camelContext="camel-1",routeId="route2",serviceName="MicrometerRoutePolicyService",} 0.0
CamelExchangesFailed_total{camelContext="camel-1",routeId="route1",serviceName="MicrometerRoutePolicyService",} 0.0
# HELP CamelExchangesTotal_total  
# TYPE CamelExchangesTotal_total counter
CamelExchangesTotal_total{camelContext="camel-1",routeId="route3",serviceName="MicrometerRoutePolicyService",} 0.0
CamelExchangesTotal_total{camelContext="camel-1",routeId="route2",serviceName="MicrometerRoutePolicyService",} 0.0
CamelExchangesTotal_total{camelContext="camel-1",routeId="route1",serviceName="MicrometerRoutePolicyService",} 0.0
# HELP CamelExchangesExternalRedeliveries_total  
# TYPE CamelExchangesExternalRedeliveries_total counter
CamelExchangesExternalRedeliveries_total{camelContext="camel-1",routeId="route3",serviceName="MicrometerRoutePolicyService",} 0.0
CamelExchangesExternalRedeliveries_total{camelContext="camel-1",routeId="route2",serviceName="MicrometerRoutePolicyService",} 0.0
CamelExchangesExternalRedeliveries_total{camelContext="camel-1",routeId="route1",serviceName="MicrometerRoutePolicyService",} 0.0
# HELP CamelExchangesSucceeded_total  
# TYPE CamelExchangesSucceeded_total counter
CamelExchangesSucceeded_total{camelContext="camel-1",routeId="route3",serviceName="MicrometerRoutePolicyService",} 0.0
CamelExchangesSucceeded_total{camelContext="camel-1",routeId="route2",serviceName="MicrometerRoutePolicyService",} 0.0
CamelExchangesSucceeded_total{camelContext="camel-1",routeId="route1",serviceName="MicrometerRoutePolicyService",} 0.0
# HELP CamelExchangesFailuresHandled_total  
# TYPE CamelExchangesFailuresHandled_total counter
CamelExchangesFailuresHandled_total{camelContext="camel-1",routeId="route3",serviceName="MicrometerRoutePolicyService",} 0.0
CamelExchangesFailuresHandled_total{camelContext="camel-1",routeId="route2",serviceName="MicrometerRoutePolicyService",} 0.0
CamelExchangesFailuresHandled_total{camelContext="camel-1",routeId="route1",serviceName="MicrometerRoutePolicyService",} 0.0

通过研究mbeans，我可以看到还有一些我也感兴趣的其他度量（例如，路由平均处理时间）

问题是，我如何使Spring靴执行器+千分尺+普罗米修斯包括那些额外的度量？

Answer 1

如果有可以启用的内容，请先检查camel度量配置。如果Camel创建分发版或计时器，则可以启用千分尺端的百分位数报告。使用Spring Boot，检查management.metrics属性，例如：

management.metrics.distribution.percentiles.all=0.95, 0.98, 0.99, 0.999, 0.9999, 0.99999
management.metrics.distribution.percentiles-histogram.all=true

对于这个问题，Prometheus JMX Exporter可能是一个快速而肮脏的解决方案，但我不确定我是否会全心全意地推荐它：

• JVM代理使事情变得复杂，因为您需要将它添加到部署解决方案中
• JMX是分层的，Prometheus是多维的，所以您需要编写和维护正则表达式来进行转换（在那里，这不是一个非常愉快的练习）
• 如果要使用另一个后端，Prometheus JMX Exporter将无法与它们一起工作
