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.

Pros

"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."
"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 has made our infrastructure more reliable."
"PRTG is simple to manage. First, you can create a template for a device, then apply it to hundreds of similar devices. That's a great advantage."
"The solution has excellent redundant features."
"The bandwidth monitoring is a very attractive feature, it can tell you the bandwidth utilization while it is attempting to connect to the host for feedback."
"The most valuable feature of PRTG Network Monitor is the different monitoring probes available."
"The alerting is the most valuable feature. I also like the iPhone app. I get alerts in an email on the iPhone app."
"It is pretty simple to use, which is always a good thing. It's been very reliable in updating us if any issues crop up."
"PRTG Network Monitor helped prevent incidents by creating an alert to the DL when servers go down, notifying me before it became a bigger problem."
 

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."
"I've encountered a challenge in my functions, particularly in adding and printing."
"PRTG Network Monitor is okay to use, but you'll need some time to analyze the data. If it can automatically locate or identify the problem area, it would be more helpful to users."
"Integration into service management ticketing systems could be better. They should simplify the integration into big service management platforms like ServiceNow, Remedy, and Cherwell. They're really into monitoring, but they don't do any self-resolution. It would be better if the company moved more into the AIOps space so that you could actually kick off some remedies. I know that you can execute some commands from the tool, but you need to develop those all yourself. It would be really handy if they had some auto-remedy scripts that they could develop on top."
"The remote probes seem to be a little bit buggy at times. They just stop working or they say they can't communicate. What we tend to do to is install the remote app onto the servers that we use. That seems to clear it up."
"Dashboards can look cluttered on smaller screens, and the UI can feel crowded when there are hundreds of sensors in one group."
"PRTG would be improved if it required less memory to run."
"PRTG Network Monitor could improve by having descriptions for the tab usages. The dashboards or interface could be easier to understand."
"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."
 

Pricing and Cost Advice

Information not available
"The pricing is okay and it is cheaper than some competing products."
"One thing I like is that when you buy sensors, it's a perpetual license, so once you buy 2,000 sensors, you've got 2,000 sensors; it's not a recurring cost."
"It is expensive."
"Licenses are very expensive, so I would like to see cheaper licensing."
"The licensing fees are billed annually and there are no costs in addition to this."
"It's a cost-efficient tool."
"Cost was a factor when selecting this solution, but it just did everything we wanted it to do."
"On a yearly basis, I believe it's between £1,200 and £1,500."

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…
