JXInsight/Simz is a revolutionary new application performance monitoring (APM) approach based on a (patent pending) highly scalable discrete event simulation engine that replays, in near real-time, the execution behavior and resource consumption of metered activities (code, requests, transactions, interactions) across an entire infrastructure of instrumented application runtimes within a single simulated (virtual) application runtime.
