I would agree with your assessment on Opsview http://opsview.org/ . It is working well for me so far. I recently built did a nearly painless build (via apt-get install blah) of it on a Debian box, and they also have a VM available.
I'm not sure why the NMIS / MRTG combo doesn't do the trick for your trending / graphing needs -- I've used plain old NMIS http://www.sins.com.au/nmis/ (which opsview includes) to do a lot of the things I have done in the past with Cacti. If there's other stuff you're getting out of cacti these days, I'd be interested in hearing that. These are all basically frontends to RRDtool, if memory serves.
Opsview has a clean (IMO) interface (no goofy Windows-like dropdown like groundworks), and does monitoring (agentless or agent-ful/agenty), trending, psuedo-useful but mgmt-pleasing network visualization (via nagviz), alerting, custom hoopla, etc..
My additional need has been configuration management for network devices, which is where RANCID http://www.shrubbery.net/rancid/ comes in. Rancid also allows a lot of nice (expect-based) mass-configuration of network devices (e.g., changing snmp passwords globally). Command-line required. There is also a (somewhat weak) 'looking-glass' plugin that comes with NMIS (and I think opsview) so that you could tie in viewing of RANCID configs from the same NMIS/opsview dashboard.
My only complaint with opsview at the moment is that the integration with MRTG and NMIS isn't very tight. You just click over to their dashboards. On the plus side, device/host configuration is shared, which is fantastic. (Also, you don't have to install them separately, which is actually a pretty big win.)
Another good thing -- if you're talking 5000 devices, agents and distributed monitoring are there for you.
This sounds like the perfect opportunity to harness the power of app partisans to fix the wikipedia article comparing monitoring software.
See http://en.wikipedia.org/wiki/Comparison_of_network_monitoring_systems . Some good info there. And probably bad info. But certainly has a good list of applications.
Also, if you like nagios (and he seems to me to be fair to a lot of packages, including ossim), you might check out some of David Josephsen's articles (or Nagios book), etc.. His site is http://www.skeptech.org/ . A decent design article is here -- Best Practices for Designing a Nagios Monitoring System --

Unfortunately, the technology identified is verboten in at least two major world religions (you can't mix those bits, it's _unnatural_). Not to mention that bringing these to market in any meaningful volume is at variance with the interests of some of the largest industrial lobbies in the world. But we might as well blame it on something goofy, since the more accurate Syriana-type background actors and machinations are just too depressing.
I disagree on the meaning of the original headline, though we will be arguing 'descriptive' versus 'prescriptive' if we wander much farther there.
If your point is that we understand the sentence without over-analyzing it, I do agree with that.
Nevertheless in the interest of science and ridiculous sentence constructions, I recommend rewriting the headline as something like 'World's Oldest Rocks Found Found' or 'World's Oldest Discovered Rocks Discovered.' That keeps most of the words, but adds an extra one which is funnier to look at, and has better mouthfeel.
Or not, but I'm voting for it even if it's not on the ticket. (That, and the two options discussed so far -- keeping the headline as it is or trashing it and starting over because it isn't strictly true even though it's clear, are both wrong, or are the same thing, or fail to account for the influence of the Illuminati and the Fed on Mom's apple pies, etc., and I'm an ideological purist, and I'm so rational and so correct that I won't listen to your rational attempts at correction, because they are not coming from whoever it was that convinced me of whatever it is I am convinced of, in the first place.)
Tried to type this ('lsb_release...') in on my ubuntu box, and accidentally typed in lsd_release -a.
Sadly, nothing happened, which makes me believe the brown distro is bad.

Haven't done it yet, however, Alan Lord does a good write-up on this: http://www.theopensourcerer.com/2009/04/23/how-to-remove-mono-from-ubuntu-904-jaunty-jackalope/
Alternately, a different finance-related conspiracy theory can be found here: http://abovetopsecret.com/forum/thread393789/pg1 and here: http://finance.google.com/group/google.finance.983582/browse_thread/thread/aad550b590f931bf .
Of course, massively bogus, though entertaining, especially if you liked (or liked some of the background sources of) the Da Vinci Code.
Alternately, my text can be de-deratiocinated by plugging it, or something not unlike it, into one of your run-of-the-mill markov chain scripties, such as the one at http://www.eskimo.com/~rstarr/cgi-bin/markov.cgi . Or via Gary Burd's python script : http://gary.burd.info/2003/11/markov-chain-generator.html
I can't reveal the source of my infos, however, here is the top secret extract from the mechanism detailed above (results will vary): You're not going to get any "sense" from me. Things make sense only when someone is trying to sell you something. If you don't believe me, well, you bought it. Beirut radio periodically rebroadcast the general's announcement, which was dubbed Communiqué No. 1. The message was ignored by President Franjieh, who remained safe inside his presidential palace at Baabda, on a letter suggesting that the General lost one billion buckaroos on that program the first time around and balks at the suggestion that lithium ion batteries are not yet ready for primetime. Remember, though, that Lutz is extremely involved in the Volt project, so it's not too surprising that he had plenty to say in response to the Palestinian guerrillas, and there were fears last week as gunmen again began erecting street barricades and kidnaping scores of civilians. [With apologies to 1976.]
