Hi, thanks for the great tool to help us profile our back-end components a lot! i have a quick question about the tool: firstly i use the visualVM jmx remote connection and have a heap-dump file in my local.
the interesting thing is the file is about less than 500 MB. but the heap size is about 8GB in Monitor tab. i think the 8 GB could be the real size in our java component. so why the hpprof file is just 400+MB? and i just also can get the instance size in 400+ level, can't reflect the real memory usage in the runtime, right?
Really appreciated if you great team can help on those concerns.
\visualvm142\bin\visualvm.exe --jdkhome D:\JAVA\jdk10.0.1
D:\JAVA\jdk10.0.1\jre. If you choose any other directory like
D:\JAVA\jre10.0.1VisualVM will start just fine. The only path, which will not work is
D:\JAVA\jdk10.0.1\jre. :-) To fix it - please uninstall public JRE 10.0.1 and install it into different directory or do not install it at all.
Thank you @thurka, you're absolutely right! I was confused because Profiler tab was missing and Sampler tab contains exactly the same buttons.
Right, Profiler tab is only available for local java applications.
