Hi Vamsy,

MAT can only trigger heap dumps from processes on the same box where the tool is running. Triggering dumps on a remote machine is not possible. Internally we also call jmap to get the dumps.

As for the question about a different tool - if you manage to connect remotely with jconsole you can use then one of the MBeans to dump the heap - com.sun.management / HotSpotDiagnostic, operations -> dumpHeap.
http://java.sun.com/javase/6/docs/technotes/guides/managemen t/jconsole.html

However, then you'll have to copy the dump to a place where MAT can open it on your own.

Hope this helps.

Krum
