As we have rolled out OpenNMS at several customer sites (apart from our
own network; site sizes range from a couple of dozens of devices up to
something like 15000 systems with lots of room for growth) and
previously were using Nagios, I very much doubt you'd be able to run
Nagios on a network with 50000 systems in it ... unless you start
stacking up multiple servers to work in parallel ...

There are OpenNMS-based installations out there with at least 48000
systems, running smoothly with detailed overview over the connected
devices ... YMMV of course, but I believe OpenNMS is your best shot here
... License and support cost for OV will cost you more than an arm and a
leg for such a large scenario, and Tivoli might not cover your
requirements (apart from the cost & performance). Both the latter we
have replaced with OpenNMS in two customer installations ... and they
are very glad they threw them out :)

When we found that Nagios was unable to cope with our (and customer)
requirements, we did an internal review of multiple FOSS systems - of
those, only few were able to cope with anything larger than 10000
systems, and most lacked important features we had on our must-have-list ...
