[Argus is] the best property valuation tool on the market but you also can't really do any advanced property valuations without Argus. It's an industry standard and while there are competitors, they do not approach the same feature set or institutional usage the Argus has.

I would recommend all system administrators use some form of network monitoring if they are not already doing so, and I'd definitely recommend people consider OpenNMS if they're shopping around. Small businesses will benefit from the low-cost of entry (it's free!), whilst getting all the enterprise features. Larger businesses can benefit from paid support plans.
However, there's no getting around the fact that you will require some advanced networking and sysadmin knowledge to get the most out of OpenNMS, or at least, be prepared for a steep learning curve. If you don't have the resources to devote this time initially, you may struggle.

- We've had a few issues with delayed alerting.
- I haven't quite figured out how to make topologies work yet, but I haven't spent a ton of time on it either.
- We've also had a bit of trouble importing some MIBs, but that usually boiled down to working with the vendor to make sure we had the right MIBs and dependencies.

Argus is the type of program that is very difficult to just sit down and figure out. Our analysts must have formal training in order to use it. The standard is a three day classroom course that is offered on a pretty regular basis.

Support is pretty good. The techs are pretty knowledgeable about the product and confident. You don't feel like they are just going through the knowledgebase and they are easy to understand. I have also never been stuck on hold for a long period of time to speak to someone.

OpenNMS's more attractive GUI and its price break were the main reasons our company chose to explore and use this product. However, it never managed to actually replace Nagios which had a much more established hold within the company. Perhaps we were over-monitoring, but our company claimed a $100k loss per hour of downtime.

- Initial adoption required quite a lot of resources and time to get everything right. Totally worth it for us; just be prepared for a gradual process that will get better and better with time.
- Once setup and running smoothly, it provides us with all the reporting we could hope for, at near zero cost.
- With OpenNMS, we're able to offer a much more reliable service to our customers, and spend a lot less time dealing with issues.
