Systems Architect at a tech services company with 51-200 employees
Flexible device polling times and extensible modules are key features for me
There are lots of reasons why I'm using it. The installer itself is basically something that can be used as a no-questions-asked type of installer. I can use it with automation tools like Chef and Puppet. I don't have to answer some random questions. I can worry about all that stuff later on in the configuration. It allows for variable polling times of devices on the network. Because it's all in text, in general, that obviously makes it easier from the automation perspective as well, to modify configuration on the fly, using Puppet and those kind of tools. It does have different modules, so you can extend the solution as you need it, or get as little as you need in the beginning, so you don't have to buy a full set of modules. You just buy what you need and expand later on.

Has reduced troubleshooting time and improved issue detection through sensor alerts and team collaboration
PRTG Network Monitor can be improved because the dashboard themes feel outdated. It should be updated to a newer version for the new Gen Z customers. The notification sound options are limited unless customized. Restarting probes after Windows updates is necessary, and there should be some kind of automatic restart. The initial auto-discovery added too many unnecessary sensors, so auto-discovery should only take the necessary sensors into consideration.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The big thing is the event management engine, which is really, really nice to use, and it comes at a reasonable price, unlike some of the competitors like Netcool from IBM. Those kinds of tools are hugely expensive and they come as resource-heavy types of solutions. This obviously doesn't require as much hardware, but it does offer similar benefits where you can manage all the events."
"It allows for variable polling times of devices on the network. Because it's all in text, in general, that obviously makes it easier from the automation perspective as well, to modify configuration on the fly, using Puppet and those kind of tools."
"In my case, I prefer to only poll interfaces that have descriptions, and the ones that don't have descriptions, I don't really want to know about them. It does allow for all these bits and pieces and adjustments, and fine tuning to get it to a point where it works for my needs."
"It does have different modules, so you can extend the solution as you need it, or get as little as you need in the beginning, so you don't have to buy a full set of modules. You just buy what you need and expand later on."
"The installer itself is basically something that can be used as a no-questions-asked type of installer. I can use it with automation tools like Chef and Puppet. I don't have to answer some random questions. I can worry about all that stuff later on in the configuration."
"I think it compares very well to all the solutions in what it offers, and also I think compared to some of them, it is much more reliable."
"We have gotten weeks and hours back from using the product."
"We have been extremely satisfied with PRTG's capabilities overall."
"The real-time monitoring feature in PRTG is invaluable to me"
"It is pretty simple to use, which is always a good thing. It's been very reliable in updating us if any issues crop up."
"The feature set is very strong compared to other products that I have used; it's great because it does everything that we need it to do, it's easy to use, and it looks great when you present it in an open office environment."
"The most valuable feature of PRTG Network Monitor is real-time monitoring."
"We can see which fiber links have been used heavily and, if they are used heavily, we can introduce more links to particular buildings or particular areas."
"The most valuable feature of PRTG Network Monitor is the dashboards. We can check to see the resources and the uptime."
 

Cons

"These kinds of solutions are more node- or device-based solutions. It would be nice in the future if they could be more data-oriented, so it would be easier for me to pull different stats based on ad-hoc requirements; but in a big, centralized database where I can pull specific things, and mix and match the way I want to."
"Improvements in data storage flexibility, such as allowing customers to specify data retention periods, would enhance PRTG."
"Sometimes the error messages are too vague and don't directly tell me what went wrong."
"We have had a few issues with the web elements, as far as the dashboard. With the dashboard, it has to be manually refreshed. Occasionally, we reboot the server, or at least web services, due to the web aspect."
"The user interface could be more modern as it is quite dated. PRTG Network Monitor can sometimes be too detailed and cluttered at the beginning, making it heavy to use."
"Integration into service management ticketing systems could be better. They should simplify the integration into big service management platforms like ServiceNow, Remedy, and Cherwell."
"The most significant disadvantage of PRTG Network Monitor is that the dashboard for NetFlow is not user-friendly at all."
"I know we're going to move to Docker applications and I understand that PRTG does some monitoring regarding this. I do not know if it is complete. If it's not yet complete, it's something they should consider improving."
"In our organization, we encounter performance issues with our PRTG probe service. I saw documentation from the vendor or Paessler mentioning that there are limitations for WMI sensors. Other than that, we are okay with PRTG."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
