With the cost of OpenNMS, it is totally worth it. Additionally, the system works on most platforms which is great. The system can be configured following how to guides and Google searches and is open so it doesn’t require specialized admins. I prefer this system and it’s …
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.
integrates seamlessly with Windows servers via WMI and PowerShell, providing deep insights into resource usage, performance metrics, and system health. It's excellent at tracking CPU, memory, disk space, and event logs, enabling rapid troubleshooting and proactive maintenance. PRTG Network Monitor also effectively monitors Fortigate devices, providing detailed data on firewall health, traffic patterns, bandwidth utilization, VPN status, and security alerts. This visibility helps detect and resolve network security issues promptly.
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.
Licensing on a per entity basis can be cumbersome for devices which have a ton of monitoring points like network switches\routers. Each sensor may count against a license, which could be a lot of you were monitoring every TX\RX of an SFP for example
A better method to easily template\copy monitors across devices
The navigation in the web GUI could be a little more straightforward in terms of the hierarchy
I would renew it because the platform has brought us many technical and economic benefits that make the cost-benefit ratio very good. Additionally, to do so does not require large investments in training, licensing or infrastructure, and at the administration level, extensive knowledge is not required to be able to bear it.
The tool is very intuitive to use and it is Windows-based (everybody knows how to use Windows) so it's easy to get into. Every time is setup in a hierarchy so if you have a good initial hierarchy design, it will really reduce administrative effort down the road.
PRTG does everything we need it to do and more. Ease of use, ease of management and maintenance and clarity of monitoring of hundreds of different types of device and service gives this a large advantage over other products on the market that I have tried. I would definitely recommend it to anyone who needs a network monitoring product in their environment and even to people who don't know they need a solution yet!
It's very important that de project's teams have different member of the TI. We have learned too late the importa of Security Analyst at the design architecture moment. We have to rebuild part of the implementation for made this big mistake.
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.
PRTG offers more versatility in monitoring when compared to the other solutions we tested. The other solutions were also limited as far as customization options, which made them less adaptable to our networks. When compared to Auvik, for instance, we prefer PRTG as it offers immediate notifications through the desktop client - not limited to email notifications as with Auvik. We also appreciate the fact that PRTG can be self/on-prem hosted vs Auvik's cloud model. This makes for an easier deployment and less firewall adjustments to allow traffic to cloud-hosted solutions.
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.
The ability to analyze multiple pieces of information in one place, especially with historical data, has saved our IT department time and headaches. It would be so much more difficult to trace an issue without PRTG, just relying on event logs and an open task manager window.
The cost is not cheap, so it's an expense that hits the bottom line like everything else. Figure in hardware costs as well, ideally a server outside of your main environment.
I keep saying this, but the historical data piece is worth so much. There's really no good way to collect all of that information in one place without something like PRTG. And that definitely saves time and money in the long run.
