I'd love to know how you configured this.   I like having useless charts generated and then emailed to me if possible. ;)

I use a package called mrtg - available for most platforms I believe.

The summary page is hand-rolled html which grabs the images from each of the mrtg-generated pages.

To figure out what interface number to use in the mrtg.cfg file, I use a linux command-line tool called snmpwalk which will dump the snmp table of the cisco router - do something like this:

[root at monitor hecnet]# snmpwalk -v1 -c hecnet hub.platinum.net | grep ifDescr
IF-MIB::ifDescr.1 = STRING: Ethernet0/0
IF-MIB::ifDescr.2 = STRING: Ethernet0/1
IF-MIB::ifDescr.3 = STRING: Null0
IF-MIB::ifDescr.4 = STRING: Tunnel0
IF-MIB::ifDescr.5 = STRING: Tunnel50
IF-MIB::ifDescr.6 = STRING: Tunnel52
IF-MIB::ifDescr.7 = STRING: Tunnel53
IF-MIB::ifDescr.8 = STRING: Tunnel54
IF-MIB::ifDescr.9 = STRING: Tunnel55
[root at monitor hecnet]# 

This shows you that interface 0 is the ethernet port, interface 5 is tunnel50, etc.   You need to enable snmp on your cisco with:

snmp-server community hecnet RO

(choose your own community string - these were just examples).
