Dear All,

I am trying to get details with respect to the disk accesses (read/writes) done by domUs by putting some monitoring code in dom0. One way to achieve this is to create all domUs in separate LVM and use some disk monitoring utility program like iostat to get the details, but is it possible to get the details without running any utility program such as putting some monitoring code in hypervisor to do the required ? I am using a tap:aio configuration to mount by domU image, and am going through blktap device driver files to get some details but till now no luck.

I have written mails earlier to this community but have never got a single reply. I am not if I am not able to put the question in a proper manner or this does not fall under anybody of your interest. If in case I am not so clear with respect to my questions, please do reply so I get a chance to rephrase by question.

It would be a great help if someone can provide some useful pointers to perform above mentioned tasks.
