How can perform ceilometer query on an instance within the instance?

Hi,

I'd like to monitor resource usage of an instance by using ceilometer. But I can query it only at a host machine running openstack layer.

Is there a way that I can achieve this?

thanks,

How can perform ceilometer query on an instance within the instance?

Hi,

I'd like I run an application which performs intensive disk i/o. Now, I want to monitor resource usage check how much disk i/o occured during a certain period of an instance by using ceilometer. But time. I can use a tool like dstat, collectd or even ganglia for clusters. I know, but, that Openstack already has the right tool for it; ceilometer.

Openstack admin can directly query it only at those information on a host machine running openstack layer. certain instance, but it's not possible within the VM instance which has no idea about where to send query and what is his instance ID.

Is there a way that I can achieve this?

thanks,
