JVM Heap Utilization Threshold
Hi All,
We are using version 8.4.1 and 8.3.1 Pega. Further we see that we often reach 82% JVM heap memory utilization. Can anyone please provide acceptable range of the heap utilization which does not trouble the performance of the application so that we can set a proper alert around JVM heap check?
Thanks,
Kiran M N

@KiranM85 It's not unusual for heap utilization to reach 90% without causing performance issues. However, it's important to monitor heap memory trends and set appropriate JVM configurations.
Regularly check for Garbage Collection (GC) throughput; anything above 97% is considered good. You can use Pega Predictive Diagnostic Cloud (PDC) or other monitoring tools like JVisualVM to keep an eye on heap memory and GC activity.
