> I'm trying to play with Spring-boot camel and metrics to expose dashboard. 
> Hawtio is a great tools to check what it's going on at runtime but no persistence is done. We would like to persist statistics in prometheus by example. 
> I configure camel context with MetricsMessageHistoryFactory as: 
>     MetricsMessageHistoryFactory metricsMessageHistoryFactory = new MetricsMessageHistoryFactory(); 
>     metricsMessageHistoryFactory.setMetricsRegistry(metricRegistry); 
>     camelContext.setMessageHistoryFactory(metricsMessageHistoryFactory); 
> where metricRegistry is injected with: 
>   /** 
>    * Srping Boot metrics 
>    */ 
>   @Autowired 
>   private MetricRegistry metricRegistry; 
> Everything is ok until I passed in OnExceptionRoute. It seems that the routeId is set to Null in this case and generate a NPE (line MetricsMessageHistoryFactory:138) in the exception route. Route causing the NPE:
> onException(NoAttachmentToProcessException.class) 
>         .routeId(RouteIds.TECHNICAL_ERROR_HANDLING.routeId()) 
>         .log(LoggingLevel.ERROR,"TECHNICAL ERROR: ${exchangeProperty.CamelExceptionCaught}")
