</blockquote><div><br></div></div><div>Yeah, we were running nexsm on our network of about 300 devices - not huge, but not tiny. The main advantage that I found was ease of configuration. With nexsm, it starts with the map fully populated with all network devices and links, and you can simply drag the devices around to where you want them. With nagvis, it starts off with an empty map, and you have to manually place every device AND every link. If you are just trying to populate a server room or something, this is fine, and probably even easer than the nexsm approach (where you would have to tell it to hide all the unwanted hosts), but when you are trying to map 300 or so devices, plus links, it quickly becomes prohibitively time consuming. And while you can reposition devices in nagvis by dragging (although I have had no end of trouble getting that to work), they aren't attached to their links, so you have to manually reposition BOTH the device and any links to/from the device. This isn't an issue with nexsm.</div>
<div><br></div><div>I also found the display in nexsm to be easier to use- you can easily zoom in and out to see more or less of the map (if you can do this in nagvis, I haven't discovered how), and the map can be as large as you want- nagvis (from what I can tell) is limited to the size of the background image you choose. Although I do prefer the icon sets with nagvis over nexsm- nexsm uses the image you set in the nagios config.</div>
<div><br></div><div>Finally, I prefer nexsm over nagvis for performance issues, although admittedly I suspect this is due to mysql, not nagvis itself. On the system I am using, I have found that when nagios is dumping stuff to the database, mysql uses pretty much all available processing power, and nagios hangs waiting for it to complete. Nexsm just reads the nagios logs directly, and while it is java, which uses a fair amount of processor, it's not as bad as mysql, at least on my OS. Also, when running nagvis, nagios has a tendency to stop updating completely every day or two, and can't be restarted until I kill the ndo2db daemon. I never had issues like that with nexsm- probably because it was just passively reading the log files, rather than trying to use an active event broker in nagios. Nexsm also just "feels" simpler to me- nagvis consists of an event broker module, a ndo2db daemon, the mysql server (although that might already be running somewhere for something else) and the web front end. nexsm is "just" a single java applet.</div>
<div><br></div><div>Keep in mind though that my opinions may be at least partially based on incomplete or incorrect knowledge of nagvis. While I used nexsm extensively until we moved to nagios 3, I have never actually managed to get nagvis running acceptably. The three separate occasions I tried it have all been non-starters. The last time I got it running for a couple of days, but between the above mentioned performance issues, and never really being able to get the maps configured the way I wanted, we quickly took it offline. Also it is entirely possible that my desired usage (as a full-network overview) is better suited for nexsm than nagvis, and a different usage might work better with nagvis. But so far, for us, nagvis has proven to not be sutable.</div>

<div>
If you are still running nagios 2, nexsm ( <a href="http://nexsm.sf.net" target="_blank">http://nexsm.sf.net</a> ) is an excellent option, one that I highly preferred over nagvis for a number of reasons. Doesn't work with nagios 3, however. I Don't know how hard it would be to fix (I suspect it is just a log parsing issue, but I don't know), but it is written in java, which I don't know, and the developer hasn't had time to work on it lately. Oh well.</div>
