[one-users] poll script return value if VM is not running

[knawnd at gmail.com]

Hi!

I wonder what $ONE_LOCATION/var/remotes/vmm/<hypervisor>/poll script has 
to return if polling VM is not running (but it can be in one of a,p,d,e 
state)?
Should it be just STATE='<vm status>' or script has to return all 
meaningful for OpenNebula variables (USEDCPU, USEDMEMORY, NETRX and NETTX)?
If all  variables listed above are mandatory then which values has to be 
assigned to them (0, -, something else or variables shouldn't have any 
value assigned) since they can't be retrieved?

I couldn't find such info in [1].

Thanks!
Nikolay.
