[mrtg] Graphing Multicast

[Geba, Scott]

How do I graph multicast correctly? 

I am using this oid for multicast due to the fact that I am trying to
graph them on 10-30G interfaces/port channels. (From Cisco's
CISCO-IPROUTE-MIB)

Target[target]:
1.3.6.1.4.1.9.10.2.1.1.5.1.1.32&1.3.6.1.4.1.9.10.2.1.1.5.1.2.32:public at x
.x.x.x:::::2

For the rest below, I just used cfgmaker to create it mirroring a
standard interface bandwidth config. 


When I do an SNMPWALK on it, I get this...

SNMPv2-SMI::enterprises.9.10.2.1.1.5.1.1.32 = Counter64: 710887360

This is on a portchannel interface. The information I get back should
rarely, if ever change. If I get back 7108887360 I should have that same
number every other time, and doing a manual snmpget does show that this
number doesn't change.  When I try to graph it with MRTG I get all kinds
of spikes and valleys every time it polls, which is incorrect. What am I
doing wrong? 

Thanks!
