is it possible to check CPU and RAM usage of the OpenVZ *host* machine from within a VM?

Question

I have purchased an OpenVZ VPS from one of the hundreds of internet hosting companies. I dont pay much for it, but lately performance has been terrible.

They are obviously overselling, but I am trying to determine by how much. Is it possible to, from within an OpenVZ VPS, check CPU usage/memory usage of the host machine?

Commands like 'top' only seem to show the usage for my specific VPS, but 'cat /proc/cpuinfo' shows the cpuinfo for the underlying host CPU

Thanks

Solution

Your vm is effectively sandboxed. without something on the host specifically giving you the info, you wont be able to get it.

edit: Also, try linnode. They've been great for me, one of the few internet companies I dont have a single complaint about :-)

+1 for using OpenVZ. Unfortunately cheap hosting do not operate properly: allocate too few resources for too many users.

Thanks for clearing that up! Also, I will take a look at linnode

This wont solve the problem in my question - shared hosting is different from virtualised hosting.
