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 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Make sure that you have the XenServer tools installed. Are you familiar with this wiki page: http://wiki.xensource.com/xenwiki/Dynamic_Memory_Control Let us know if that helps.

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.
