DO I need to increase the heap memory

My Atlassian Jira instance in windows server is running with 2 GB heap allocated. Always in the the system info, I see 80 -85 % full. But never system was unresponsive. Should I increase the heap ?

    Hello Rilwan,

    Since the system info shows only 80-85, then it is not required to increase the heap. But, it is worth monitoring  and understand the gc behavior

    Hello Rilwan!

     

     When looking at your Java heap behaviour, there is no anomaly. So you don't have to increase the Java heap memory size. Infact there is room to reduce this 2gb heap size as pointed out by GCeasy tool.

     

    Fig: GCeasy tool is reporting you to reduce Heap size if needed

     

     But be advised that JVM Memory has multiple memory regions. Java Heap is the predominate region but there also other regions as shown in the below image. To learn about different watch this video - Different JVM Memory Regions.

    If your memory utilization on the container/device is 80 - 85% it could be coming from other regions. But as Unni mentioned you don't have to change heap size or any other region size, if there is no degration in the response time of the application.
