I'm not aware of any mechanism in JConsole to send the output anywhere, other than via the clipboard. > After this processing, the process in a "top" display shows > the following : > 22175 star 21 0 266m 23m 11m S 1.0 4.6 0:14.61 java > (where 266m is the virtual memory, and 11m the resident one). The top virtual number is just what's in the memory map for the process, so that includes files, code, non-Java stuff, etc., as well as the JVM heap. The resident memory number is the pages that happen to be in RAM at the moment. > Compared to the numbers I see in the jconsole VM summary below, > these memory figures seem to show a gross disproportion, or am I > interpreting this wrong ? > Snapshot 1 > Current heap size: > 785 kbytes This is just the combined virtual size of the new and old generations; it does not include PermGen. > Maximum heap size: > 65.088 kbytes How big the new + old can get, if needed. > Committed memory: > 1.984 kbytes Includes the JIT's code pool, C heap, Java heap, PermGen, and various other bits and pieces the JVM knows about. > Committed virtual memory: > 270.980 kbytes > Total physical memory: > 516.920 kbytes > Free physical memory: > 6.852 kbytes > Total swap space: > 1.297.564 kbytes > Free swap space: > 1.234.376 kbytes All of the above are for the entire system, not just this one process. > Snapshot 2 > Current heap size: > 1.828 kbytes The heap has expanded a bit. > Maximum heap size: > 65.088 kbytes This can't change. > Committed memory: > 2.452 kbytes Increased due to heap expansion plus probable enlarging of the code pool, C heap, PermGen, etc. Nothing unexpected here. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
