>  
> After setting up Micrometer Observations with @CamelObservation on a spring-boot application the MicrometerObservationTracer handling of log statements in a route is problematic when log statements is not static.
> If we use the ${body} in a log statement we create a new tracing metric for each unique body processed by the application.
> A simple route like will create 10000 tracer metrics the application needs to keep in memory:
> {code:java}
>         from("timer:java?period=100")
>             .setBody()
>                 .simple("${random(10000)}")
>             .log("Lets create a lot of  metrics: ${body}"); {code}
>  
> The problem will be a lot worse if the body is always unique and of a significant size.
> A example of the problem can be found [here|https://github.com/bjoraru/camel-observation-metrics-problem].
> Keep it running for a few minutes and check http://localhost:8080/actuator/metrics
