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.

PRTG Network Monitor can be improved because the dashboard themes feel outdated.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."
"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."
"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."
"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."
"Currently, we are competing in the market with SolarWinds and ManageEngine, they are good, but we come out winning."
"The feature I like is that it can easily do a lot of mapping."
"PRTG Network Monitor is perhaps the most accurate tool we have used to monitor the capacity of the WAN connection."
"I think net flow is PRTG's most valuable feature because it doesn't cost much for us because the net flow sensor is already included in the PRTG license. We can monitor our traffic in our proxy and router."
"I really love the activity library. It gives the flexibility to discover data and metrics about my interface and data server."
"The solution has excellent redundant features."
"If someone were looking for a basic monitoring tool for servers and networks, I would recommend PRTG Network Monitor."
"The auto-pause for sensors during maintenance windows is awesome, as there are no false alerts till now and the built-in SNMP tester tool has saved me multiple times during setups, making PRTG Network Monitor a one-stop monitoring solution for my industry."
 

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."
"In terms of sensors and probes, it would be really cool if PRTG had a purely Azure-based solution. We had to install a probe on one of our cloud servers and then let that probe out from there. It would be really cool if it just monitored Azure without having to install something on the device."
"Map designer could be improved by adding more flexibility to the links instead of the straight line."
"I would like to see Office 365 monitoring. Essentially, it doesn't do it."
"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."
"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."
"PRTG Network Monitor can be improved because the dashboard themes feel outdated."
"The remote probes are okay. I think that there could be more sensors available, especially with newer technologies coming along."
"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."

"When you buy PRTG, everything comes in one bundle. Licensing is very easy."
"PRTG Network Monitor is very expensive."
"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."
"I rate the licensing for PRTG Network Monitor an eight out of ten."
"It's a cost-efficient tool."
"We pay for PRTG Network Monitor annually. The price is approximately 10,000 rupees annually."
"I'm paying something like €1000 per year for the maintenance. I've got unlimited sensors."

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…
