PRTG Network Monitor is the flagship offering from German software company Paessler, for monitoring local and wide area networks (LANs & WANs), servers, websites, apps, and more.
PRTG is well suited for networks of all sizes, however it can be a bit cost-prohibitive when needing to monitor slightly more than their no-cost tier offers, or if you need to monitor roughly have of the amount of devices offered in their first paid tier. That said, it scales and works well in our small network of 300+ devices. It would likely excel in larger enterprise/data-center type of networks as well. It also works very well for remote-site monitoring, which reduces our need for on-site IT staff at our other location.
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.
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
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.
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].
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.
