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.
Basically, Opennms will auto-discover the ranges you give it, detecting an assortment of services and snmp, then automatically poll what it discovers on 5 minute intervals and report outages. You can configure thresholds levels in the snmp data to generate alarms. You have to add whatever setup you want for external notificatons - they are off by default but you can set up email destinations, a jabber group conference, etc. There are near-infinite other options, of course, but that covers most of what you are likely to want.
I found this pdf with a much nicer overview: http://www.google.com/url?sa=U&start=2&q=http://www.ukuug.org/events...
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.
I wouldn't be too hopeful without some extra work. I have a pair of Dell 5324's and am not getting the link info, but it works on a bunch of different cisco models. It does collect the bandwidth data from the Dells - the rest might be a matter of adding more of the oid trees to the 'included' view but the Dell switch management is kind of weird.
Per http://www.opennms.org/index.php/Linkd you need the .iso.org.dod.internet.mgmt.mib-2.ip.ipNetToMediaTable values.
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.
I hadn't tried a Mac before - the default settings don't look that promising. It should all boil down to getting the oid trees you need exposed, though.
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.
Might be a good topic for the opennms list.
