Claus Ibsen updated CAMEL-23383:
--------------------------------
Fix Version/s: 4.x
> Add JFR runtime instrumentation for exchanges, processors, and endpoints
> ------------------------------------------------------------------------
>
> Key: CAMEL-23383
> URL: https://issues.apache.org/jira/browse/CAMEL-23383
> Project: Camel
> Issue Type: New Feature
> Components: camel-jfr
> Affects Versions: 4.20.0
> Reporter: Federico Mariani
> Priority: Major
> Fix For: 4.x
>
>
> The existing _camel-jfr_ module (CAMEL-16056) only instruments
> startup/shutdown lifecycle via _StartupStepRecorder_. There is no runtime
> instrumentation, per-exchange, per-processor, or per-endpoint JFR events are
> not emitted.
>
>
>
>
> Libraries like
> [hibernate-jfr|https://github.com/hibernate/hibernate-orm/tree/main/hibernate-jfr]
> demonstrate the value of per-operation JFR events for production
> diagnostics. Camel should offer the same capability for route execution.
>
>
>
>
> Proposed JFR events:
> - *CamelRouteEvent*: routeId, exchangeId, elapsedTime, failed
> - *CamelProcessorEvent*: exchangeId, routeId, processorId, processorType,
> elapsedTime
> - *CamelEndpointSendEvent*: exchangeId, endpointUri, elapsedTime, failed
> - *CamelExchangeEvent*: exchangeId, routeId, endpointUri, elapsedTime, failed
> - *CamelExchangeFailedEvent*: exchangeId, routeId, exceptionType,
> exceptionMessage
> - *CamelRedeliveryEvent*: exchangeId, routeId, attempt, maxAttempts
>
> Implementation approach proposal:
>
>
>
>
> Camel already has the interception infrastructure — InterceptStrategy,
> EventNotifier, and RoutePolicyFactory used by _camel-opentelemetry2_ for OTel
> spans. The JFR implementation would follow the same wiring but emit JFR
> events instead.
>
>
>
>
> Why JFR:
>
>
>
> - Zero overhead when recording is disabled (JVM JIT short-circuits
> begin()/commit())
>
>
> - No external collector needed, open the .jfr file in JDK Mission Control
> - Captures JVM-level context (CPU, memory, GC, threads) in the same recording
> alongside Camel events
>
>
> - Safe for always-on production use
>
>
>
>
>
>
>
> This could either extend the existing *camel-jfr* module or be a new
> *camel-jfr-runtime* module.
