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.

Quotes from Members

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

Pros

"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."
"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."
"The reliability of the solution means we are doing less work trying to figure out issues and optimize systems, as it is already supplying us with the information that we need."
"The solution is scalable."
"Ability to create a dashboard inside software monitoring."
"We have asked questions of their technical support and they have a very good response time."
"I can customize the port as per my need and the real-time monitoring feature that is already provided to me."
"I can create my own program sensor. This means I can add extra monitoring capabilities into the already fundamentally strong foundation."
"It will take care of all your monitoring needs, pretty much, but just be conscious of scale."
"The most valuable feature of PRTG Network Monitor is real-time monitoring."
 

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."
"PRTG Network Monitor can improve Layer 2 and Layer 3 network maps and the GUI more user-friendly. Additionally, they should bundle the features so I can monitor everything on one particular device."
"The technical support response time is still prolonged, and the resolution can be better."
"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."
"There's always room for improvement. The high availability feature is good, but it's an area that PRTG could marginally improve. For example, in PRTG, both servers have a different IP, but it would make things a lot easier if they were bound by a single IP."
"I would like to have a VM version that can be installed on a cloud such as Azure. We're using Azure, and we're eliminating on-premise servers. It would be helpful to have a PRTG version that can be installed on the Azure cloud."
"The setup aspect of it and getting devices working needs improvement."
"There seems to be a big jump from the basic scan to the really thorough scan. There is a big jump in the quantity of sensors it uses for certain things. One minute you might get ten and then the next you get 200. There seems to be a big jump between the two at times."
"For smaller networks, I would recommend this solution. That said, if the network is complex, I would recommend a company evaluates another product instead."
 

Pricing and Cost Advice

Information not available
"The price is actually on the cheaper side. If you're going with the unlimited license code, it's very cheap compared to competitors unless you're going for something free, like Zabbix. But you get what you pay for, and it doesn't have the full suite of products or tools like SolarWinds or a ScienceLogic."
"We pay nothing for it. Its 100 sensors have allowed us to put a magnifying glass on some systems, providing an extra layer of detail. Therefore, our outgoing is nothing and our incoming is a lot of useful data that we can react to proactively."
"The pricing is comparable."
"On a yearly basis, I believe it's between £1,200 and £1,500."
"PRTG Network Monitor is not that expensive, so I like it cost-wise. There's no additional cost apart from the standard licensing fees. On a scale of one to five, with one being the cheapest and five being the most expensive, I would rate the cost of PRTG Network Monitor a two."
"The pricing is reasonable for the features provided."
"I'm paying something like €1000 per year for the maintenance. I've got unlimited sensors."
"The price is pretty comparable."

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…
