Hi list,

This is probably my first email to the list :)

I'm using XCP 0.5 as of now and I'm very happy with its performance and

I'm trying to identify two realtime parameters of a running VM using

# xe vm-data-source-query  data-source=memory_internal_free vm=vm1

# xe vm-data-source-query  data-source=memory vm=vm1

On a stable VM (the VM whose target memory is not changing rapidly) these
commands are giving correct output but if I set a VM's target memory and try
to check its internal free memory Im getting old value... and after a minute
If I fire the same command to check internal free memory it gives me an
updated value which is correct.

I want to fetch the realtime data with "# xe vm-data-source-query
  data-source=memory_internal_free vm=vm1"   but  cant get.. the output is
always a minute old

could someone please shed some light on this.?? or am I missing anything ??
  or is there any way by which I can force xe command to update its database
Determining free memory is tricky. Make sure that you have the
XenServer tools installed.

Are you familiar with this wiki page:

Let us know if that helps.

Thanks for the reply Todd.

Regarding the xen tools, they are installed inside the VM and I'm getting the updates but late, approximately a minute or two.

Link appreciated but I'm unable to find any useful information regarding my problem from it.
