The only commercial solution that comes close to what we need as an enterprise is the product suite from SolarWinds, but its expensive when your talking 8-12,000 IP enabled devices.

Intermapper works great for us, handles dependancies, has configurable timers for flapping, and all the usual + traps. Remote Access is nice, engineers can bring it up from anywhere on their screen with full maps displayed rather than just a list of probes. It's cheap. For logging Splunk works well.

We've looked at free options but nothing seems to do the job without a ton of scripting and multiple packages.

What we don't like is the cost of Intermapper Flows – ideally we'd like to have NetFlow monitoring on everything, but at $300 USD per router + maintenance, it's hard to justify. If anyone knows of decent NetFlow analysers that are less costly for 200+ routers, I'd like to hear about them.

Subject: [nznog] Nagios vs. OpenNMS vs. SomethingElse
If you had it all to do over again, what would you use for network monitoring: Nagios, OpenNMS, or something else entirely?

I care about availaility, latency, loss, jitter, and trap handling for interface up/down, loss of power, etc. Sensible behavior in situations where parent routers/links are flapping is also important.

I would very much appreciate input from folks monitoring 1000+ network elements.
