JVM monitoring landing page in Pega Predictive Diagnostic Cloud

High heap usage in the Old Gen and Eden Space, even during system idle time, could be due to various reasons such as memory leaks, inefficient garbage collection, or high object creation rates. You can use Pega Predictive Diagnostic Cloud (PDC) to monitor and analyze your system's heap usage. If the heap usage remains high even during idle times, it might indicate a memory leak or inefficient garbage collection. You can use the JVM monitoring features in PDC to analyze the heap usage and garbage collection activities. If the issue persists, you might need to adjust your JVM settings or review your application for potential memory leaks.
