If this is a serverside application, then presumably you have at least the
minimum GC logging flags on?
-Xloggc:<pathtofile> -XX:+PrintGCDetails -XX:+PrintTenuringDistribution
I would regard these as the absolute minimum information for tools to be
able to help you - no JVM server process (and especially not one in
production) should ever run without these.
It's also worth noting that whilst VisualVM is great for getting for a feel
of an application, it has much less information to draw upon than are in
the logs (and it is, of course, point-in-time & has to be run whilst the
application is running).
