Which is the best non-visual profiling tool for Glassfish?

I have the web application on Glassfish 3.1 (no vnc connection, only ssh access), and have some problems with memory there, would like to profile it a bit. A time ago used VisualVM for local needs, but seems it will not suit there as it is graphical. Tried to use simple HPROF profiler (http://download.oracle.com/docs/cd/E18930_01/html/821-2418/beafn.html#beafo) but for some reasons no file is created with profile info.. So, would be great to use some lightweight tool, which would create files with pro开发者_如何学运维filing results for futher investigation

Thanks!
