OK, I've been tracking this conversation, installed/configured/started OpenNMS and have discovered everything and in fact, edited service-configuration.xml as recommended.
I'm sort of comparing this to Zenoss which I had to stop (snmp conflicts) to run OpenNMS.
I can see each port on the 48 port managed switch and go to 'View Node Link Detailed Info' but it doesn't tell me much about the device/computer plugged into a specific port.
Let it soak overnight. It goes out of its way not to kill your network and has a long startup delay and times between polls - all tunable in the xml files, of course.

While I don't want to be quick to dismiss OpenNMS, it seems to fall way short of Zenoss so I'm thinking that there's a bunch of stuff that probably needs to be tweaked.
It mostly does the right thing by default, although if you want bandwidth graphs on the non-IP ports on your switches you either need to set it up for each node or change snmpStorageFlag to "all' in datacollection-config.xml
I am interested in a comparison with Zenoss - but wait until you know your way around opennms. Just ask on the opennms list if it doesn't do something you expect.

Thus far (and admittedly this is premature), I find Zenoss a lot beefier but I spent a ton of time setting it up the first time until I figured things out whereas I spent comparatively no time setting OpenNMS up. But I have learned things along the way, especially getting SNMP set up on everything I could. ----
I got the impression that NetDisco would actually tell me the IP Address (perhaps reverse the DNS name) of the device connected to specific port on my managed switch. I didn't go for the NetDisco route for install because I didn't like the idea of getting a bunch of CPAN perl modules installed rather than using rpm packages.
Assuming it can get the info from the switch, it will - and give you clickable link to the other device's node info.
---- That's something that I've never been able to do in Zenoss and if it's possible, I don't know. I think Zenoss only has forums and not mail list and I truly don't like forums.
This is a Dell PowerConnect 6248 'managed' switch so I would think it could. I enabled monitoring on all of the ports just in case. That would beat the brains out of the spreadsheets I've been maintaining on interconnects between patch panel, switch and office map to identify but since this is newly rewired, I am not having much trouble.
One thing that is throwing me for a loop is that it says all the Macintosh systems are a 10Mbps SNMP connection but on the Macs themselves, they clearly indicate 1Gbps. This somewhat tracks all of the pain that I have had with SNMP collection on the Macs, which on Zenoss has been less than spectacular. For example, I get installed software list, total installed memory, total hard drive space, free hard drive space on all Linux and Windows systems but only get total hard drive space and total installed memory on Macs. On Zenoss, I have resorted to ssh collection on Macs because snmp collection just sort of sucks.
