What FusionReactor is
FusionReactor is an application performance monitoring product from Intergral GmbH for finding why applications perform poorly or fail. Its real-time APM includes continuous profiling, database monitoring, anomaly detection, full trace capture, call-tree information, and method-level detail. Profiling covers code, memory, threads, CPU, and garbage collection, with source-map support and continuous alerts. The monitoring agent is available for Java and ColdFusion applications and can run on-premise or be added to Cloud; the maker says data can remain local. Java and ColdFusion telemetry can be exported to OpenTelemetry-compatible backends such as Datadog, New Relic, Grafana Cloud, Honeycomb, and Splunk. The Developer Edition targets development and test environments. Platforms listed are API, Linux, macOS, self-hosted, web, and Windows. Cloud usage beyond allowances switches to on-demand for the rest of the billing period.
