ZVision is a diagnostics and tuning tool instrumented into AVM that offers a uniquely detailed view of all performance aspects of an application, including thread, memory, and IO profiles. ZVision is always-on and has zero performance overhead, making it the ideal tool to use in production deployments. ZVision helps systems administrators to identify performance issues as they happen and take rapid corrective measures. Since it is integrated into the AVM, there is no set up required and the information is always available.

 

 

ZVision is a performance analysis and debugging tool built into the ZingVM. ZVision allows users to monitor Java application behavior on-the-fly in production environments using a standard web browser.

 

ZVision complements traditional Java performance tools with rich, always-on, real-time visibility into the performance of both the application and the ZingVM. It provides critical information for addressing some of the most challenging performance bottlenecks with much greater efficiency.

Key Features:

Real-Time and Always-On. No frustrating delays between occurrence of a performance event and accessing related information. Identify performance problems as they happen in production. No need to restart applications.

 

Zero Performance Overhead. Safely use the feature to gather and view performance data without any fear of impacting production deployments.

 

Threads View. Browse what threads are doing, and whether they are working or waiting (and if so, for how long). See an instantaneous snapshot of stack trace for all threads.

 

CPU Usage Profiler. Identify execution hotspots as candidates for optimization, see activity level of application or ZingVM components over time.

 

Hot-locks. Spot expensive locks causing your threads to block and preventing multicore scaling.
System call profile. Identify system calls that occur frequently or take a long time to complete.
No-setup. ZVision requires no configuration and no code changes.
