[c-nsp] using snmp views effectively

[Peter Krupl]

Hi Group,

I guess nobody has a working example, as i is just to cumbersome to
handle. If someone from cisco is reading, then please, please, please
add a vrf snmp view feature, with basic IF-MIB support based upon the 
vrf membership of the interface.

I have a small example below, nothing I use for production
just something i made as an example.

It gives basic system information, and IF-MIB if index 8 & 10.
Th catch here is it is only possible based on ifindex, som you might
try: snmp-server ifindex persist

Newer versions of rrdtool have support for "Aberrant behavior detection
with holt-winters forecasting" of data in the RRD. See the website.
