JConsole OperatingSystem mbean

I am looking at an OperatingSystem MBean through JConsole. It is giving me the attribute "TotalPhysicalMemorySize" as being 2048MB. However, the actual server has closer to 3000MB. This is the same for many other processes I connect to - if the actual drops below 2048, the display is correct. Is 2048MB the max it can report?

Any ideas?

The OperatingSystem MBean reports the total physical memory size of the machine that the process is running on. It's not the machine that JConsole is running if it's a different one.

What OS are you running on? What tool do you use to find the total phyiscal memory size when comparing with the value shown in JConsole?
