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 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."
"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."
"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."
"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."
"As far as network monitoring and analysis, I cannot think of a more intuitive and flexible product on the market today."
"It has made our infrastructure more reliable."
"PRTG is integrated on Windows."
"I would recommend this solution because it's great for monitoring network traffic and producing reports."
"The most valuable features of PRTG Network Monitor are user-friendly, and the graphical interface is good for all the network devices that are mapped in this organization. It's very easy to find reports for any devices that we are looking for."
"Over the approximately two years that the company has been using this product, it has been very stable."
"To others who are interested in using this solution, I would recommend it, it's a decent product."
"PRTG Network Monitor is user-friendly and takes just one click to install the solution in Windows."
 

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."

"Sometimes the error messages are too vague and don't directly tell me what went wrong."
"There's always room for improvement. The high availability feature is good, but it's an area that PRTG could marginally improve."
"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."
"The setup aspect of it and getting devices working needs improvement."
"A room for improvement in PRTG Network Monitor is its sensors. Its application technology sensor, such as the IAS, .NET, etc., needs some improvement because it doesn't work as expected. For example, the IAS sensor doesn't give immediate information, and the information you get from it isn't of good value. The web GUI of PRTG Network Monitor also needs improvement because errors keep popping up if it's not been updated to the latest version. What I'd like to see in the next release of the tool is end-to-end topology mapping for the business model, and that should be required. There has to be a technical map. Technical mapping and topological creation are missing in PRTG Network Monitor, so I would like to see those in the future."
"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."
"PRTG can fix that, but it's only good for small workloads."
"This product can be improved by updating the net flow interface. The one that is in place works – I can get all the information I need from it – but it is a little bit clunky."
 

Pricing and Cost Advice

Information not available
"We have an unlimited perpetual license, so we just pay support costs and it can scale throughout the organization."
"Licenses are very expensive, so I would like to see cheaper licensing."
"It is about £4,500 for the first year, then about another 15 to 20 percent annually after that. So, we are looking at about £1000 running costs a year. When you think about how much an outage costs per minute, it's negligible."
"PRTG Network Monitor is cheap."
"The pricing is okay and it is cheaper than some competing products."
"We are licensed for 2500 endpoints."
"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."
"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."

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…
