Memory Footprint Diagnostics

1) Generate dump file

Http://127.0.0.1:8081/manage/actuator/heapdump

2) Start the Jhat tool for analysis

Jhat-port 7000 D:/heapdump

3) View the in-memory object occupancy

http://127.0.0.1:7000/oql/

Select S from java.lang.String s where s.value.length >= 5000

Very strong!!!
