FusionReactor 2026 Release

FusionReactor has released version 2026 of its agent today.  Download it here.

• Enhanced Metrics & Observability

  We’ve significantly expanded the data you can extract from your environment, offering deeper insights into ColdFusion and Java performance.
  • Expanded Request Tracking: New, high-fidelity metrics for HTTP, database transactions, and messaging systems.
  • ColdFusion DB Pools: Database pool statistics are now exported directly, allowing for better connection management visibility.
  • Improved JVM Metrics: More granular data on memory, garbage collection, and thread states.
  • Format Flexibility: You can now toggle metric naming and recording formats to suit your stack using the following flags:

  • Toggle Names:-Dfr.observability.metric.names=[fr|otel|all]
  • Prometheus JVM Style: Enable via -Dfr.observability.metric.prometheus.jvm.enabled=true

• Zero-Config Native Alerting

  Sending critical alerts just got easier. This update introduces the ability to send emails natively from the agent without an external SMTP server, removing the friction of credential management and firewall configuration.

• Debugger Improvements & Fixes

  • We’ve refined the interactive debugger to handle modern Java environments and specific Lucee nuances:

  • Java 21+ Support: Fixed variable listing issues encountered on the latest LTS versions of Java.

  • Breakpoint Control: Added support for enabling/disabling breakpoints per location.

Note: These settings are not persisted across restarts. Enabled breakpoints will reset to trigger on all locations upon agent restart.

• • Lucee Source Mapping: Improved accuracy for showing correct source files when breakpoints are triggered.

Tip: Lucee users not using the debugger can disable this to save on class processing using -Dfr.lucee.debugger.fullfilename.enabled=false.

 Reliability & Core Enhancements

• • Lucee Error Capture: Improved exception handling for Lucee requests. If you find the capture too sensitive for your specific application logic, you can disable it via -Dfr.lucee.exception.request.enabled=false.

• • UI Tunneling: Significant improvements to the reliability and stability of the UI tunnel connection.

• • General Maintenance: Includes various bug fixes and performance optimizations.

Legacy Component Notice*

The Observability Agent is no longer included within FRAM as the project is currently inactive.

• • Access: Uninstallers and legacy installers remain available on the official GitHub repository.

• • Recommendation: We strongly recommend migrating to modern, industry-standard tools such as Grafana Alloy or the OpenTelemetry Collector for direct telemetry ingestion.

Note on the Observability Agent: While we continue to support the core FusionReactor Agent’s OTel export capabilities, the standalone “Observability Agent” (formerly part of the FRAM suite) has been deprecated in favor of the superior performance and community support found in native OTel collection tools.
