Question

我已经编写了自定义插件，用于监控Jboss Operational Network（JON）上的camel路由。但在RHQ server / JON中，没有添加任何指标用于监控。

在RHQ-agent日志文件中，我能够看到以下内容。

2012-12-04 13:47:13,515 DEBUG [InventoryManager.discovery-1] (rhq.core.pc.inventory.InventoryManager)- Executing discovery for [Srikanth Custom Service] Resources...
2012-12-04 13:47:13,515 DEBUG [ResourceDiscoveryComponent.invoker.daemon-1] (org.rhq.plugins.jmx.MBeanResourceDiscoveryComponent)- Discovering MBean resources with object name query template: org.apache.camel:type=routes,*

2012-12-04 13:47:13,531 DEBUG [ResourceDiscoveryComponent.invoker.daemon-1] (org.rhq.plugins.jmx.MBeanResourceDiscoveryComponent)- **[0] services have been added**
2012-12-04 13:47:13,531 DEBUG [InventoryManager.discovery-1] (rhq.core.pc.inventory.InventoryManager)- Discovery for [Srikanth Custom Service] resources completed in [16] ms

这里我发送部署在ON JON上的插件代码。

RHQ-plugin.xml的

              description="Number of completed exchanges"/>
    <!-- END of Custom metrics -->
   </service>   
   <!-- END of service -->
</plugin>
<!-- END of plugin-->

如何将此ExchangesCompleted指标添加到JON服务器以进行监控？

请帮帮我。

Answer 1

为了确保，您是否知道JON为Red Hat提供的Fuse产品提供了一个插件？

我知道在撰写您的消息时，它尚未得到支持和提供，因为JBoss品牌的Fuse产品尚未发布。

希望，但是现在，你已经使用了这些插件而不必重新发明轮子。

干杯。

Answer 2

虽然我对Fuse产品几乎一无所知，但我怀疑你根本没有在

中找到属性名称的正确表达式

<metric property="ExchangesCompleted"

特别是在这里使用对象名称模式时：

  <c:simple-property name="objectName" readOnly="true" default="org.apache.camel:type=routes,*" />

确保对于org.apache.camel:type=routes,* ExchangesCompleted的对象，{{1}}确实存在。

也许首先要通过不使用对象名称模式来缩小范围，而是使用一个具体的对象名称。
