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.
If there are a number of different protocols and devices to monitor PRTG is really an all in one solution. There are network specific solutions, telephony solutions, server solutions, etc - but this tool can do anything. Even if you don't use this tool as your main "monitoring solutions" every IT professional should have access to this tool for at least troubleshooting purposes. If you are looking for something specific built for a task you may be able to find [a] more direct and easy tool to use that would be easier and quicker to setup as customization is not needed.
Very, very configurable. You can create all kinds of monitors for all kinds of things. Plus it has loads of suggestions out of the box. It can get complicated but monitoring is complicated. Pretty decent interface and good support - active community.
I really liked how easy it was to add alerts by SMS. So easy to setup.
I like their sizing models (for purchase). We're actually small enough that we are free. But it's not free as in stripped down - it's free because we don't use many "sensors" and don't honestly have the need.
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.
The probe service can be quite resource-intensive. This can cause false-positive readings from some sensors sometimes.
The software gets updated very regularly. Whilst this is usually a good thing to fix bugs etc, it does meantime downtime of the monitoring quite often while they are installed.
The ability to create Maps from Libraries. Very specific issue but a lot of people have been asking for it for years and it is still not available.
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.
I am giving this a 6 simply because I have never had to contact support. The online documentation is adequate for most things, and the user-maintained knowledgebase is excellent. The few times I have run into issues that were not easily resolvable with intuitive UI, I was able to find the answers that I needed either in the PRTG-provided documentation, the knowledgebase, or with a quick online web search.
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.
I have deployed and tested three products for evaluation I found [PRTG Network Monitor] very easy to deploy, the deployment literally took not more than one hour including basic configuration and network discovery. After deployment few configuration changes and creation of maps, reports and little tweaking is required. [Then] it would go through its process of recommendation that took some time to complete, while [on] other hand other software's took lot of time to install and configure. And features were also missing, which resulted in decision in favor of [PRTG Network Monitor].
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.
