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
?
Determining free memory is tricky. 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.
Thanks,

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.
Regards,
Rishi
