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PRTG Network Monitor can be improved because the dashboard themes feel outdated.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

"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."
"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 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."
"I would recommend this solution because it's great for monitoring network traffic and producing reports."
"This solution provides us with the needed feedback on our IT infrastructure. It allows us to grab all the information from a single point of view."
"Its proactiveness is its most valuable feature. We already know when we come in, in the morning, if a server or site is down, as opposed to someone telling us."
"Ability to create a dashboard inside software monitoring."
"The sensors and probes are great, nice and lightweight, they don't take up too many resources on the system. We just deploy them out and they start reporting instantly."
"It is great for service level agreements and can comply fully with internet monitoring or any interface."
"The solution has definitely saved us time and money."
"We've managed to cut down on our P1 escalations by around about 70 percent."
 

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."
"Although the reporting module is functional, I feel it is a bit clunky compared to the rest of the interface, and it would benefit from being polished for future use."
"To have the additional features costs a lot. It's too much."
"Their penetration within the market could be much better. If their pricing was lower, even though it's reasonable now, it might help them achieve this."
"This solution is a good product so far, but I haven't been using it long enough to know how it could be improved."
"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."
"It needs to have more monitoring on end-user devices."
"When using PRTG Network Monitor it is beneficial if you have prior experience with it, the user interface could improve."
"When you email the support team, they take three to seven days to respond and resolve simple issues."
 

Pricing and Cost Advice

Information not available
"The price was pretty good, very competitive."
"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."
"We are using the basic PRTG that we can download for free. For now, we only need to monitor less than 100 devices. For more than 100 devices, we would need to buy a license. PRTG is much cheaper than SolarWinds."
"PRTG is now available as PRTG Enterprise Monitor, and the price varies depending on the total number of sensors the customer buys"
"We have unlimited devices and sensors, and it is a bit pricey, but we do have unlimited sensors. With all things considered the price is fine, related to the solution itself. PRTG Network Monitor is good value for money."
"The pricing is very low compared to other solutions."
"Our licensing costs are 10,000 euros over three years."

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…
