Sample current output before creating graphs

[BSOD2600]

It would be handy to see a sample of the output for snmp scripts, in the 'create graphs for host' screen.

For example, lets say I've got a device with 8 interfaces. I'm not sure which ones are up and passing traffic. Instead of creating graphs for all 8, waiting 10 minutes and then looking at each graph. I would be handy if Cacti returned a sample of the In/Out bytes for each interface. The same could go for other snmp scripts... disk queries returning the current space. My running processes script return the current cpu/memory usage, etc.
