Next to the rrd requirements, you may want to put some pruning in place for the eventlog and syslog tables.

Size of storage per device depends on what is monitored on it. But as said in other answers the data files itself do not expand.

I mentioned in a previous e-mail that we’re rolling out a deployment of Observium, and we absolutely love the product. I know that it’s designed as a historical data gathering tool, but I am concerned about the storage requirements for the system. I have approximately 600 routers and switches on my campus, and eventually would like to get my servers involved (pushing the device count beyond two-thousand), and I’m concerned at the storage requirements for this. I couldn’t find this information anywhere online, so I figured I would check with you guys.

Does Observium have any kind of roll-over archiving for device history beyond a certain point, or will it continually just grow the data in the files?
