So I have been able to setup Zenoss.
I have manually added some Cisco devices...
1) 3640 Router
2) Some Catalyst switches
So I have been able to add the devices.
1) for the cisco 3640 router it shows snmp is working/connecting
Under Monitoring Templates->Device (/Network/Router/Cisco)
It has data sources for sysUpTime, cpu5min, mem5minFree
2) Switch example
Under Monitoring Templates->Device (/Network/Switch)
It has data sources for sysUpTime
And snmp-walk from the console works, but I don't have any info in the graphs. I have previously used Cacti and that worked (gave me port stats) before, I really like this product and have been trying to switch since its got a lot more in it.
I have tried changing the snmp version in Zenoss but that didn't seem to work.
Any help would be great, as I very new to Zenoss and have not done much with SNMP
I don't monitor any Cisco devices myself, but my guess is you'll need to install one ore more of the Cisco zenpacks (http://community.zenoss.org/community/zenpacks) to get more details.
Alright I figured it out. I made a few tweaks, but 90% sure that the one that did it was....
Under Advanced -> Daemons
I noticed that zenperfsnmp was stopped, so I started it and I have statistics coming through.
The other thing I did which may have mattered is I turned on logging for the cisco router to go to zenoss
on cisco router (in conf t mode): logging <ip for zenoss>
