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.
Riverbed Modeler is well suited for wireless, wired, ZigBee, and Cisco networks. All these scenarios are efficiently designed and simulated using Riverbed Modeler, as all the devices are available in its object pallet, so we just need to drag and drop for the best scenario design in the given dimensions. The simulation results are around 95% accurate. However, it is not suited for data security, as data encryption algorithms are not available in Riverbed Modeler.
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.
Riverbed Modeler needs to improve the scenarios of LAN MAN WAN, as the available scenarios under all of these follow a simple area structure that's not connected to the ISP when it comes to simulation. This generates dummy traffic.
Riverbed Modeler also needs to work on the selection of result sets so that, as with most designed networks, we can select any result parameter to show. All the parameters are displayed, whether they are relevant or not. It needs to display only relevant result parameters to select.
The back-end TCP/IP model needs more clarity to expose the structure to some changes.
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.
The only thing comparable to OPNET is Packet Tracer, which is basic and very limited. Packet Tracer in terms of tool comparison between the two is like OPNET's stone-age relative.
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.
It comes with a costly paid license, but simulating the network before actual deployment saves a lot of costs, in case after deployment we feel performance is not good and we need to change. This would waste a lot of money, but Riverbed saves this money.
Its OPNET GURU academic edition is available free of cost, but with limited functionality, which is good for students in maximum case. This will degrade our sale of Riverbed Modeler.
A one-time investment in Modeler saves a lot of cost regarding networks, topology, designing, and provides a lifetime license with updates.
