The existing remote poller functionality with the addition of being able to dictate what poller gets what set of devices would be fantastic.

Okay thanks I think I read that, I did a lot of ‘scouring’ and searching and a little of my own testing. I think that’s where I was getting confused on running cron tasks and how to point rrdtool and mysql, but im sure I can find those with their respective kb on how to modify the configs.

You need to make your central system use rrdcached, and then configure rrdcached to accept remote connections from the hosts which will be polling. MySQL needs to accept connections from these too.
The easiest way is then to just install the same version of Observium on the remote poller, and point it at the central system for MySQL and rrdcached (it doesn't need local rrd access, provided you're using rrdtool 1.6.x). Don't run the cron jobs on the satellite systems though, that'd be really bad. :)
There's a post about basically the same thing here : http://blog.best-practice.se/2017/10/scaling-observium-horizontally.html
The post is focused on having multiple pollers running next to each other to spread load, but the principle is the same. I'll probably need to modify the code a bit to let you mask out devices, like i said before.

Could you point me in the direction of doing it that way? Do I install an observium ‘instance’ on the remote site and then somehow push/pull the data back to the central site for processing?

We can't do agent stuff because our poller is too tightly integrated into the database (read: it's functionally impossible without basically rewriting virtually the entire poller/discovery systems). The closest you can do is running a poller and dragging MySQL long distance. Not ideal, but should work ok if the connectivity is reliable and not horrible latency.
You do need to make sure that the observium instances are kept at exactly the same version at all times, though!

On the proxy snmp, makes sense, because the few apps and stuff that we have seen did not work. I know ZenOSS can do it (on-premise agent), and PRTG puts an ‘agent’ that reports back to the central server which is nice, but we really like the observium slack integration and the reports/graphs and all the other stuff it can detect.
Even if we had to install like an observium instance on-prem I could do that, what we don’t want to do is end up with 30 installs that have to all be updated/managed/alerted all individually because over time its not something we can scale confidently.

Hi,
I've never seen a usable solution for proxying SNMP. It seems like something that would break horribly almost constantly.
There is the vague ability to run a poller on a remote system so long as the remote system can reach MySQL and rrdcached on the Observium server. It's probably pretty reliable with good connectivity, but the MySQL latency would perhaps make the polling slower. Doing it this way might require us to modify the poller wrapper slightly to allow you to mask out devices you don't want to poll on the central install.

The networks aren’t huge but there’s a lot of them (25-30). VPN’s are not going to be an option for every site , there are some IP overlap and not a business case outside of this one that will let us go that route for everything.
We have tinkered with several of the different how-tos on snmp-proxy without success. We are using a handful of the ‘example’ alerts right now and that’s covering a lot of what we need (up/down and port usage) but I was thinking once we got this working how we wanted, someone would have other real world things that we haven’t considered.
