I have a RHEL 3 machine that is part of a VMWare cluster.

In VMware mgr Im told the machine has 24Gb of RAM
As built it had 8 GB of RAM
Looking at /proc/meminfo Im told

  • [root@vmware1 root]# cat /proc/meminfo
    total: used: free: shared: buffers: cached:
    Mem: 275017728 261877760 13139968 0 37883904 72368128

    CommitLimit: 688484 kB
    Committed_AS: 1868008 kB
    MachineMem: 25165088 kB

.. Which makes it look like ~268Mb. I don't really want to unrack it and count chips.

Where do I find 'the truth' (as pertains to this..)?

This is really unclear. VMWare is a company, not a product. What VMWare product are you using? Assuming you're using ESXi: are you running that command on an ESXi console or on the guest? What good would "counting chips" do if it's the guest that you're concerned about? – MDMarra Jul 26 '12 at 19:45

Looks to me like the amount of memory in your machine is 24 GB.

Essentially, there's a virtual machine for ESX running your service console. That's what the MemTotal value is showing. The ESX Service Console virtual machine has 256 MB of RAM. Machinemem is the total amount of physical RAM in the server, which is 24 GB.

So when I ssh to the machine thats a VM (of sorts) too? With 268mb of RAM allocated to it? – ethrbunny Jul 26 '12 at 21:26
@etherbunny Hard to tell with the limited information you've given, but I'd guess that yes, you're still working within the context of of the ESX VM, so you're still seeing the memory allocated to it under memtotal. – HopelessN00b Jul 26 '12 at 23:21
