Hi Eric,

	I found that in the docs for mrtg 2.16.  I tried it since the
values I get from the snmpwalk are not integers, I need the number of
lines returned:

Counted SNMP Walk

    In other situations, an snmpwalk is needed to count rows, but the
actual data is uninteresting. For example, counting the number of
mac-addresses in a CAM table, or the number of simultaneous dialup
sessions. You can get MRTG to count the number of instances by
prepending the OID with the string CnTWaLK. The following will retrieve
the number of simultaneous VOIP calls on some routers:


3:public at myrouter

But not working right...

What is "CnTWaLK"? Those should not be there. Might not be your only
problem but it's a start.
