[Xen-users] Finding free memory

[Rushikesh <rushikesh.jadhav@xxxxxxxxxx>]

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 
features.
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 ?
I already tried /etc/init.d/perfmon restart but with no luck :(

Regards,
Rishi
