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.

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?
