Hi Claus Thanks for that clue. I tried something like follows as I see the method dumpStatisticsAsJson() is already implemented in org.apache.camel.component.metrics.routepolicy.MetricsRegistryService class.
Hope this is a sane way of trying to get something out from the method. *<camelContext xmlns="http://camel.apache.org/schema/spring"; id="myCamelContext"> <propertyPlaceholder id="placeholder" location="classpath:appConfigs.groovy" /> <routeBuilder ref="VMMVendorIntegrationRoute"/> <route id="metrics-dump"> <from uri="timer://foo?fixedRate=true&period=15000"/> <bean ref="metricsRegistryService" method="dumpStatisticsAsJson"/> <log message="JSON Dump - ${body}"/> </route> </camelContext> <bean id="metricsRegistryService" class="org.apache.camel.component.metrics.routepolicy.MetricsRegistryService"> <property name="metricsRegistry" ref="metricRegistry"/> <property name="prettyPrint" value="true"/> <property name="jmxDomain" value="org.apache.camel.metrics"/> <property name="useJmx" value="true"/> </bean>* However, I get exception [Camel (myCamelContext) thread #3 - timer://foo] WARN org.apache.camel.component.timer.TimerConsumer - Error processing exchange. Exchange[Message: [Body is null]]. Caused by: [java.lang.NullPointerException - null] java.lang.NullPointerException *Looks like this method doesn't take any arguments. Why should this exception show up? Is there a work around for this. I even tried setting some dummy value in exchange Body.. Now I get a different exception as follows. Any clue how I can make a call to the method? * java.lang.NullPointerException at org.apache.camel.component.metrics.routepolicy.MetricsRegistryService.dumpStatisticsAsJson(MetricsRegistryService.java:158) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at org.apache.camel.component.bean.MethodInfo.invoke(MethodInfo.java:408) at org.apache.camel.component.bean.MethodInfo$1.doProceed(MethodInfo.java:279) at org.apache.camel.component.bean.MethodInfo$1.proceed(MethodInfo.java:252) at org.apache.camel.component.bean.BeanProcessor.process(BeanProcessor.java:171) at org.apache.camel.management.InstrumentationProcessor.process(InstrumentationProcessor.java:77) at org.apache.camel.processor.RedeliveryErrorHandler.process(RedeliveryErrorHandler.java:448) at org.apache.camel.processor.CamelInternalProcessor.process(CamelInternalProcessor.java:191) at org.apache.camel.processor.Pipeline.process(Pipeline.java:118) at org.apache.camel.processor.Pipeline.process(Pipeline.java:80) at org.apache.camel.processor.CamelInternalProcessor.process(CamelInternalProcessor.java:191) at org.apache.camel.component.timer.TimerConsumer.sendTimerExchange(TimerConsumer.java:165) at org.apache.camel.component.timer.TimerConsumer$1.run(TimerConsumer.java:73) at java.util.TimerThread.mainLoop(Timer.java:555) at java.util.TimerThread.run(Timer.java:505) [Camel (myCamelContext) thread #3 - timer://foo] WARN org.apache.camel.component.timer.TimerConsumer - Error processing exchange.
