红帽全球峰会220.12. MetricsRoutePolicyFactory
此工厂允许为每个路由添加一个 RoutePolicy，该路由使用 Dropwizard 指标公开路由利用率统计。此工厂可在 Java 和 XML 中使用，如下例所示。
如果您只想检测几个所选路由，而不是使用 MetricsRoutePolicyFactory，而是定义您要检测的每个路由。
从 Java 中，您要将工厂添加到 CamelContext 中，如下所示：
context.addRoutePolicyFactory(new MetricsRoutePolicyFactory());
context.addRoutePolicyFactory(new MetricsRoutePolicyFactory());从 XML DSL 中，您定义一个 <bean>，如下所示：
<!-- use camel-metrics route policy to gather metrics for all routes --> <bean id="metricsRoutePolicyFactory" class="org.apache.camel.component.metrics.routepolicy.MetricsRoutePolicyFactory"/>
<!-- use camel-metrics route policy to gather metrics for all routes -->
<bean id="metricsRoutePolicyFactory" class="org.apache.camel.component.metrics.routepolicy.MetricsRoutePolicyFactory"/>
MetricsRoutePolicyFactory 和 MetricsRoutePolicy 支持以下选项：
| Name | default | 描述 |
|---|---|---|
| useJmx | false |
使用 |
| jmxDomain | org.apache.camel.metrics | JMX 域名 |
| prettyPrint | false | 在以 json 格式输出统计信息时，是否使用用户用户打印 |
| metricsRegistry |
允许使用共享 | |
| rateUnit | timeunit.SECONDS | 指标报告器或以 json 转储统计时使用的单位。 |
| durationUnit | TimeUnit.MILLISECONDS | 指标报告器中使用的持续时间单位，或者在将统计信息转储为 json 时。 |
| namePattern |
|
Camel 2.17： 要使用的名称模式。使用点作为分隔符，但您可以更改。名为 |
从 Java 代码中，您可以存放来自 org.apache.camel.component.metrics.routepolicy.MetricsRegistry 的 ，如下所示：
com.codahale.metrics.MetricRegistry Service
MetricRegistryService registryService = context.hasService(MetricsRegistryService.class);
if (registryService != null) {
MetricsRegistry registry = registryService.getMetricsRegistry();
...
}
MetricRegistryService registryService = context.hasService(MetricsRegistryService.class);
if (registryService != null) {
MetricsRegistry registry = registryService.getMetricsRegistry();
...
}
