The virtual interface (IP alias) doesn't have it's own network statistics ... 
it's part of the parent interface (eth0), we currently don't support using 
interface names like "eth0:0".

You can set the IP address-based monitoring for IP alias, but it'll read the 
statistics of the parent interface too - for example:

--8<--
eth1:0    Link encap:Ethernet  HWaddr 00:22:33:44:55:66  
          inet addr:192.168.1.100  Bcast:192.168.1.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
--8<--

can be monitored by:

--8<--
check network myipalias with address 192.168.1.100  # note: will find interface 
for 192.168.1.100, which is eth1 in this case
--8<--

or:

--8<--
check network mynet with interface eth1  # note: statistics include the 
interface itself and all its IP aliases
--8<--


Best regards,
Martin
