Systems Architect at a tech services company with 51-200 employees
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PRTG Network Monitor can be improved because the dashboard themes feel outdated.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."
"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."
"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."
"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."
"The most valuable feature is the dashboard interface. It's very clean, it's very simple to use."
"The tool is integrated with our email for the alerts."
"The reporting module is easy to configure."
"Stable solution for monitoring networks and bandwidth, with multiple functions and features such as NetFlow Collector, graphical monitoring, etc."
"The remote probes are very useful. They allow us to provide a reference across different areas in the network. In trying to localize issues, that's very useful."
"I would be happy to recommend PRTG; I have no qualms with it whatsoever, it does what we need it to do and is flexible."
"Stability-wise, I rate the solution a ten out of ten."
"The technical support seems to be quick, clever, and has a comprehensive knowledge base online, which is fantastic."
 

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."
"The scalability of this solution could improve as well as the automated provisioning of the infrastructure."
"They need to address the slowness issue that sometimes occurs with PRTG Network Monitor."
"It's expensive to maintain."
"For smaller networks, I would recommend this solution. That said, if the network is complex, I would recommend a company evaluates another product instead."
"The solution could be improved by increasing the way that it polls the different engines which we feel is quite slow."
"The free version only gives us 100 free sensors to use. It would be nice if there was double that."
"The setup aspect of it and getting devices working needs improvement."
"The automation should be improved."
 

Pricing and Cost Advice

Information not available
"PRTG is now available as PRTG Enterprise Monitor, and the price varies depending on the total number of sensors the customer buys"
"While I am not the person who deals with pricing, I would say that we pay around 1000 pounds a year."
"I would like better pricing models for smaller businesses. The free version is fantastic, but it's too restrictive. If they could just get up to 200 sensors for a reasonable fee for on-premise, I would give PRTG my credit card right now."
"It is expensive."
"We are using the premium version of PRTG Network Monitor. The price of the solution is a bit higher than competitors but it is worth the extra money. However, it would be helpful if the price was lower."
"We've got the unlimited package... I believe it was around the £15,000 per year mark."
"We have an unlimited perpetual license, so we just pay support costs and it can scale throughout the organization."
"All monitoring system is close to the same pricing scheme."

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…
