I have a Java application, and I'd like to monitor it using Java VisualVM (jvisualvm).
However, in the VisualVM window very little data can be seen. Also, I can't take a heap dump.
Here is a screenshot of what it looks like, with another test app I wrote:
I can monitor memory usage, classes loaded and threads. Heap dumps, performing GC as well as sampling is disabled.
I have tried adding -Dcom.sun.management.jxmremote to VM arguments, as described here. This is showing up in the Installation Details window. However, it does not appear in the Java process arguments. (should it?)
I also tried to click the button in my test app until an OutOfMemoryError occurred. No heap dump; that is not weird as Heap Dump on OOME is disabled.
What could I do to solve this?
