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.

Alerting precision has reduced incident response times and improved department-level network visibility
The auto-pause sensor during the maintenance window is good without any false alerts, and it prevents me from getting flooded with alerts during planned maintenance, helping department heads understand their own network usage better. It has reduced incident response time by giving clearer ownership of each alert, ensuring alerts go to the proper recipient. SNMP testers and auto-pause are among the best features of PRTG Network Monitor, which is particularly useful for different departments such as HR and finance, where alerts can be filtered accordingly. The alerting features and dashboard of PRTG Network Monitor are very helpful, especially in our industry. However, the dashboard can look cluttered on smaller screens, which is one negative aspect. PRTG Network Monitor has impacted us positively; we have stopped getting flooded with alerts during planned maintenance or unplanned outages. Compared to others, this gives specific alerts very quickly and helps department heads understand their own network usage better, thus reducing incident response time so that each alert has clear ownership.

Pros

"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 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."
"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."
"The most valuable feature is the notifications, as long as you spend time and think about what and when you want to be notified, it's always accurate, it is always there, and I find things out before my Internet provider."
"We like the solution's report writing and the way that it compiles the system's information from around the network and brings it all back into the central site and the interface."
"PRTG Network Monitor offers a single-pane dashboard where we can monitor all the servers on one single screen, helping our team detect a failed server quickly and saving time that was previously spent checking each server manually, which in turn also reduces downtime."
"My advice to others is if you can't afford SolarWinds and those other expensive solutions, PRTG Network Monitor is the best value for money."
"The installation of PRTG Network Monitor was simple and straightforward."
"The most valuable features of PRTG Network Monitor are bandwidth utilization, user-friendliness, all past report simple retrievals, and timeout features. Additionally, if the solution does go down it is simple to bring it back."
"The most valuable feature is the dashboard interface. It's very clean, it's very simple to use."
"To others who are interested in using this solution, I would recommend it, it's a decent product."
 

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."

"When it comes to third-party integration, one of the things we were looking at was putting some sensors onto our firewall, for instance. If there were a little bit more documentation and some step-by-step guides around that, that would be useful for us."
"There is room for improvement in this solution for the performance and third-party monitoring protocols. They need to be updated to the latest ones."
"PRTG's application monitoring sensor is not strong and could be improved, and I've also had some issues with it crashing during upgrades."
"PRTG Network Monitor can improve by adding prevention and detection features."
"The desktop app is terrible."
"We would like to monitor certain aspects of the user experience. We should be able to analyze the cause of end user experience, bad or good, so we can do some research and development on our own."
"We need something that is more predictive; we would prefer if it wasn't a solution that was corrective and instead offered predictive insights so that we can handle problems before they even occur."
"We run it in a cluster, so we have two that run together. The cluster behind it is sketchy at times."
 

Pricing and Cost Advice

Information not available
"While I am not the person who deals with pricing, I would say that we pay around 1000 pounds a year."
"Licenses are very expensive, so I would like to see cheaper licensing."
"In my company now, we are using the free version."
"Pricing for PRTG Network Monitor is a nine out of ten. It meets my company's budget and monitoring requirements. My company is on a perpetual license."
"PRTG is now available as PRTG Enterprise Monitor, and the price varies depending on the total number of sensors the customer buys"
"We pay for a perpetual license and we have a support fee."
"One thing I like is that when you buy sensors, it's a perpetual license, so once you buy 2,000 sensors, you've got 2,000 sensors; it's not a recurring cost."
"It's a cost-efficient tool."

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…
