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."
"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 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."
"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 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."
"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."
"The most valuable aspect is the diverse range of features it offers."
"The best feature is that it lets me know what is going on. I need to know if something has gone down, I need to know if something is running very slowly. PRTG tells me that."
"The solution is easy to manage and the reports are very accurate."
"We use the remote probes a lot for our branch offices. Instead of deploying the full instance of PRTG, we'll put a remote probe out there. This simplifies the whole deployment for us."
"With PRTG, we normally know of issues with our servers before anybody reports them."
"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."

"The solution could be better and faster when it comes to performance."
"Maybe in the future there will be room for improvement, but currently, there is nothing pressing that I can think of"
"PRTG Network Monitor should improve the NetFlow dashboard, there is no flexibility, and the NetFlow is not meeting the business needs. Additionally, they are missing part of the configuration management."
"The reporting features look very technical and that can be improved."
"While the desktop app is good, they could slightly improve it. We would like it to be a single pane of glass. At the moment, you can only see certain portions of information. You have to scroll through to make it more granular. We want them to develop the desktop app to be more user-friendly."
"The technical support service should be improved."
"They just released a newer version of the desktop app, a beta version, that I have been trialing out. I prefer the older version, only because of how the layout is designed"
"It's expensive to maintain."
 

Pricing and Cost Advice

Information not available
"We have an unlimited license for this solution."
"The price of PRTG Network Monitor is more expensive than other solutions, such as OP Network Manager."
"The price was pretty good, very competitive."
"PRTG is now available as PRTG Enterprise Monitor, and the price varies depending on the total number of sensors the customer buys"
"When you buy PRTG, everything comes in one bundle. Licensing is very easy."
"Sensors on free version can run out quick."
"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."
"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."

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…
