No memory usage details or graph for my Cisco devices.
I have various Cisco devices ( catalyst switches, ios routers, ios-xe, etc), but none of them are showing any memory usage details in observium. I was surprised by this as observium did a remarkable job of recognizing and displaying information for things that most snmp tools do not, Qnap for example. It does recognize my Cisco devices and reports back on just about everything, but memory. Other tools I tried, such as Manageengine, PRTG, etc reported the memory with no issue. So, I'm skeptical that there is anything wrong with my snmp setup.
I would really love to get memory usage for my Cisco devices. If anyone has any suggestions, I'm all ears.
Thanks
However, in the process of trying to find you a link to their community support, I discovered something that may be worth trying first. If you can confirm that it resolves your issue, then IMO we should consider tweaking our default appliance.
Their docs note that Debian (as of Squeeze) does not automatically include SNMP MIBs. I'm no expert in the area, but a quick google suggests that this may be the cause of your missing info! On that doc page it appears that there are 2 options, either install from Debian "non-free" repo (free of cost, just not a "free" software license) or configure Observium to use MIBs that are included.
Looking through the appliance build code, I can see that we are using the Observium MIBs, but our config doesn't quite match theirs. Perhaps the additional info will be enough?
I.e. edit the line in /etc/snmp/snmp.conf that looks like this:
So instead it looks like this:I suspect that restarting SNMP is required for the new setting to take effect. Rebooting is always another option... If that still doesn't resolve it, perhaps it's worth trying to installing MIBs from Debian non-free?
Also it's probably worth checking that you are using the latest version of Observium (and if not update it). IIRC there has been at least one new release (perhaps 2?) since we last rebuilt the appliance (which we'll be doing it again soon). FWIW the docs on upgrading are here. A community member has also submitted a suggested update script.
Hope that helps.
