There are some serious deficiencies in Netview as far as I can
tell--and I'm curious if a) they're valid, and b) what folks are using
to work around them.

SNMP v2/v3 - limited/no support
Given that Netview's support of v2 is incomplete, and support of snmp
v3 isn't even in the works, I'm curious what others are using in place
of Netview for these tasks?  

MIB polling calculations with History - can't do it? 

Unless I'm missing some hidden functionality, there's no way to
monitor a MIB variable's change in value over time.  For example,
suppose I'm monitoring packet loss and my device provides MIB counters
for packetDiscards and totalPackets.  To arrive at a % packet loss
over a given interval in time, I'd like to take the packetdiscards at
time t2 subtract is from the last sample at time t1, and divide that
by the totalPackets counter at time t2 minus total packets at t1:

 discards(t2) - discards(t1)
 ----------------------------------     * 100  = packet loss %
 totalpackts(t2) - totalpackets(t1)

Is there a way to do this with Netview...and if not, what are people
using to do it?  Lots of cron scripts?  


Anybody using this?  Netview seems to speak nothing of it and I'm not
sure if it's worth purusing. 

TIA for any advice or insight!
