Has good network visibility
The primary use case is for monitoring and troubleshooting. We also use it for security.   The correlation of data in Apex helps to get full visibility of the entire enterprise. Apex is where we get the end-user experience score from one to ten. Network visibility is the most valuable feature.…

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

"Network visibility is the most valuable feature."
"We did some research, found PRTG, and I spoke to another company that used it, they really loved it so we went ahead got the free license initially, did a trial, found it absolutely amazing, and then bought it."
"Technical support is helpful."
"The scalability is good, you can improve a remote host or the clustering, giving you the flexibility to monitor another infrastructure remotely."
"The most valuable feature is the ability to span multiple technologies and multiple vendors."
"It is a user-friendly solution."
"The initial setup is very simple."
"PRTG gives us true visibility of the downtime of particular circuit functions, so if a circuit is up but not routing traffic, I will know with this tool and can write a customized script for a sensor to detect specific things."
"We have evaluated a lot of software and we found PRTG Network Monitor the best solution."
 

Cons

"The pricing and AI can be improved."
"The setup aspect of it and getting devices working needs improvement."
"Mostly, this software has sensors for devices to monitor specs and you can build or develop or modify various sensors, according to your company's needs. But you may need to do that with coding or plugins or with the support of Paessler AG, the manufacturer."
"PRTG's documentation could be improved."
"In our organization, we encounter performance issues with our PRTG probe service. I saw documentation from the vendor or Paessler mentioning that there are limitations for WMI sensors. Other than that, we are okay with PRTG."
"I am not sure the solution is giving me all the needed feedback that we need. When something goes off on our IT infrastructure, it does tell me. However, it would be nice if it gave more intuitive information, e.g., the hard drive has gone up by 60 percent in an hour."
"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."
"Users need to buy the more expensive licenses if they expect to be able to scale."
"There's always room for improvement. The high availability feature is good, but it's an area that PRTG could marginally improve. For example, in PRTG, both servers have a different IP, but it would make things a lot easier if they were bound by a single IP."
 

Pricing and Cost Advice

"It's expensive."
"The ability to use the base version with 100 free sensors is great. The cost on other packages can be very reasonable."
"If you're looking for a cost effective software I’d suggest this product."
"At the moment I'm only using 500 sensors. I pay yearly, so it's a cost that's easily swallowed."
"Licenses are very expensive, so I would like to see cheaper licensing."
"The price of PRTG Network Monitor is reasonable for the features that the solution provides. They charge you per monitoring, not per node, it is per port that you need for a device."
"The licensing fees are billed annually and there are no costs in addition to this."
"We have an unlimited perpetual license, so we just pay support costs and it can scale throughout the organization."
"We have an unlimited license for this solution."

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…
