Why just don't add the service "MiniStats" to host host-0072?, that
way you give "domU vhost-0072-01" as parameter to check_xen. The
plugin always prints the domU name in the status info:

"WARNING: $DOMU seems to be dying (Time=$TIME) (MEM=$MEM) (VCPU=$VCPU)
(STATE=$STATE)";
"WARNING: $DOMU seems to be paused (Time=$TIME) (MEM=$MEM)
(VCPU=$VCPU) (STATE=$STATE)";
"CRITICAL: $DOMU seems to be crashed (Time=$TIME) (MEM=$MEM)
(VCPU=$VCPU) (STATE=$STATE)";
"OK: $DOMU seems to be up (Time=$TIME) (MEM=$MEM) (VCPU=$VCPU)

So, if you see that the MiniStats service is critical, you can check
what's the host name on the status info.
