I attempted to disable and re-enable the device with no luck. However, after a prolonged network outage (while I was reorganizing my cables in the MDF) every thing started working again. It was quite odd, but my guess is that the router in question my have registered an inaccurate time for one reading (just after reboot while it was on GMT -7 instead of GMT -7 AZ) and that is why the graphing stopped.
But it was very odd none the less.

Subject: Re: Cacti - Stopped graphing one device
Since nobody else chimed in, I guess I will. Just to let you know, I don't use Cacti, instead I use Zabbix to do the same thing (and more). Does Cacti have a function to disable a device if can't pole it for what ever reason? It may simply be disabled, but I would think it would re enable itself again once it could talk to the device again. Could the SNMP group or permissions change for that group during the upgrade and when you added the "new" device into Cacti you used a different group? Does Cacti have any logging that may say what is going on?
Just some basic things I would check for and I am sure you have already been down this same path, but I thought I would offer anyway.

One more piece that may help in solving the Cacti mystery. If I add a new device and new graphs for the same device then the new graphs work, but the old ones still do not. As such I am fairly sure it is purely a Cacti issue. If there is a good answer as to why and how I can get the old ones working, I would rather keep my historic data.
Other wise, there is nothing like building a new history, free from the past ;)

Subject: Cacti - Stopped graphing one device
Ok, I recently made changes to my router and rebooted it (many times) and since then Cacti will not graph the device. It graphs other devices and I can get useful data from the router using snmpwalk / snmpget so, what is the deal?
Any thoughts?
