I have a demo version of InterMapper for linux (http://www.dartware.com). It's probably the best monitoring tool I've ever used, but historically, it's only been available on Mac, until now. It's very very fast, and takes very little resources. Has auto-discovery, and it just plain works great. Oh, and it's very cheap compared to most other commercial products. I'm currently evaluating some monitoring products which need to keep track of a few hundred network devices, and several hundred network links (traffic, interface down, etc..). Right now, I'm using Nagios (http://www.nagios.org) and Cacti (http://www.raxnet.net), however, Nagios is a nightmare to administer with this many devices (edit 3 config files to add or remove a single device), and Cacti is not really really scalable enough at this point to handle this many links. There's a threaded daemon available for Cacti, but it's not fully mature yet, and the release version of it is very tedious to set up with this many devices. Besides device monitoring, I need 2 more things. I need to be able to keep historical traffic data for all of our links, and I also need something that will generate an "executive report" every week which lists the percentage of network uptime, a listing of outages, and also a list of the links which exceed an average of 60% utilization any day of the week. Unfortunately, Intermapper only provides the monitoring portion of this. It has some graphing capabilities, but not really a full fledged database of past data that I can go back and look at like with Cacti or Cricket. Also, it doesn't seem to offer any sort of executive reporting option. I could write something if I could figure out how to pull info from it, and ideally, I would like it if I could make intermapper's traffic polling save the data to an RRD database. Has anyone tried this? I'm looking at some other products also, however, they are much more expensive, and unfortunately, many of them are like 4 different products hacked together into one web interface, which is fine and dandy, but typically, at least one of the products hacked in is something that sucks. Otherwise, does anyone have any recommendations for a decent monitoring/reporting package? Free is good, but not a requirement. Ease of administration is a must though because there are just too many devices and links to have to add them using a tedious process. Also, the monitoring program must not only check for down devices, but also alert when a device has a down interface (like a frame link or something). Both Nagios and Intermapper do this. Big Brother is not what I'm looking for. Nagios is close, except for the administration part of it. Cacti comes close for traffic management, and will probably fit the bill when the new version comes out, but it's not ready yet. Using Nagios and Cacti, I could very easily write something in Perl that would generate a weekly report. Still kind of a hack, but at least I would have control over what it does. But I'm still willing to pay money if I can find something that does it all well, and is not going to take up obscene amounts of my time for day to day administration.
