So my question is, do you have any good experience with HW-systems that are actually dealing with this amount of devices or is there any tuning possibility (without losing functionality) we could try to reduce the pressure on the system?
At the moment, the closest I have access to is a system monitoring 882 devices, but it still isn't in full production mode (meaning, they still have more devices to add).
So, a bit sorry for dragging up this old thread, but I figured it would be as good as starting a new one (-:
I'm an old NAV-user (previous "job"), and haven't used it in a while. We use some commercial systems at work, that in ways does the same as NAV (though, most of them does some of the things far more un-userfriendly than NAV). Thinking of trying it out, partly because I know it has some nice features, and partly to try out new/improved features since last time I used it.
First round I'm only going to add routers and switches, which is about ~1500 units. All Cisco. Last time I used NAV, was with far less devices, so, this time, especially when taking Morten's reply above into consideration, I guess I actually need to "plan ahead", so that I get a system that can handle this amount of devices.
It also might be possible that we add servers at some point, but that's further up the road. I don't have an estimate of the number of servers, but we're talking at least 1000 of them (including VM's) -- probably more.
We also have ~1700 access points, but these are controller-based, so I guess they don't have much use to be added to NAV. I.e. I'm not even sure they speak SNMP for themselves (only via the CAPWAP-tunnel). Maybe only for monitoring of uptime, but, meh, we already have plenty of tools for that.
Anyways. What hardware requirements are we looking at here? In terms of storage, CPU, memory. I guess we need to have two servers; one for NAV, and one for the PostgreSQL. Based on your experiences with ~900 units; should I expect to double the hardware, in order to handle ~1500 units? Keep in mind that I don't want to upgrade this setup if we go down the road where we add servers as well (but I guess they impose less load per unit, compared to switches/routers that speaks SNMP, so not sure how much more overhead we need?).
Not sure if the system load is very different depending on what NAV-features one wants to use? 'Arnold' and 'Syslog analyzer' are two things that comes to mind that we won't be using.
