Easy to set up with good documentation and helpful support
I'm using it for a customer The packet flow switch is the most valuable aspect of the solution.  It's an easy product to set up. We can scale the solution if we need to. It's stable.  The documentation is well-written and quite useful. It's compatible with other products.  Under the pocket flow…

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

"The most valuable feature is utilization."
"Because we are doing proactive monitoring instead of reactive, the end users don't even see that there is something wrong."
"It helps us to assist our customers to isolate problems. If it is us who is having the problem, then we can use it to streamline the process."
"The product is stable. I have never had any issue where we have lost an InfiniStream, or visibility from that particular InfiniStream, throughout the bank."
"We have seen a lot of return on investment: We have been able to recover radios in the field, we know exactly what is going on, we cut down fines from the service commission, and we have seen a measurable decrease in mean time to know, cutting troubleshooting down by days as we can now see the issues."
"We are attracting customers in good sized numbers as we advertise and market this solution."
"It allows us to get quicker resolutions. We can see exactly what is using up the bandwidth, so we can assist end users."
"The packet flow switch is the most valuable aspect of the solution."
"I like the mobility of the PRTG Network Monitor and ITOps Dashboard."
"The simplicity of the software is great."
"It allows me to detect problems with the network, and it helps users propose the solution to resolve the problem."
"It is easy when it comes to dependencies of devices, so if your router goes down, the three or four switches behind it will automatically be paused so that you don't get multiple alerts."
"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."
"My opinion is that this solution is not very expensive."
"The product is simple and easy to implement."
"The solution has excellent redundant features."
 

Cons

"There is a timeout feature that we have been asking for awhile."
"The solution is not great, but it is not bad."
"Only problems that we have had are fiber issues going into the TAPs or vSTREAMs, which are usually local site issues."
"I would like to see an improved level of stitching between IPs."
"The stability depends on who is using the tool, because you only can get as much out of the tool as you put into it."
"The NetFlow Collectors could handle more flows per minute."
"Being able to manage the packet flow switches in nGeniusONE would be great."
"It can be scalable. It just costs too much."
"I am not sure the solution is giving me all the needed feedback that we need."
"Integration into service management ticketing systems could be better. They should simplify the integration into big service management platforms like ServiceNow, Remedy, and Cherwell."
"PRTG Network Monitor can be improved as there is a lot of manual cleanup needed, which could be reduced."
"PRTG Network Monitor could improve interaction with customers by offering direct support involvement instead of just mail responses."
"I would like the ability to monitor Cisco IRS devices."
"I would like to see Office 365 monitoring. Essentially, it doesn't do it."
"PRTG Network Monitor can improve Layer 2 and Layer 3 network maps and the GUI more user-friendly."
"The dashboarding definitely needs improvement."
 

Pricing and Cost Advice

"The price is a little high."
"This product could be cheaper."
"It can be scalable. It just costs too much. With a company as big as ours, it gets too expensive to accommodate every single site."
"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
"The scalability is good, but it comes at a cost. E.g., if you need 100 InfiniStream because you are sending gigs or terabytes of data to one InfiniStream, then you will have to purchase another InfiniStream, which are not cheap."
"I would like it to be more scalable with less spend."
"We bought a license for 4000 sensors."
"It is about £4,500 for the first year, then about another 15 to 20 percent annually after that. So, we are looking at about £1000 running costs a year. When you think about how much an outage costs per minute, it's negligible."
"The price of PRTG Network Monitor is reasonable."
"The pricing is not too bad. It's not massively expensive, and the ability to upscale or even downscale licenses every year is brilliant for us."
"We've got the unlimited package... I believe it was around the £15,000 per year mark."
"We looked at PRTG and SolarWinds. From a cost side perspective, compared to PRTG, and from what you get back from it, PRTG was sort of a hands down the winner."
"We've got 1,000 nodes and I believe it's a few hundred quid a month."
"Right now, the smallest sensor pack that they have is just a bit out of range for me, as a business. This kills me, as I need the product. Therefore, there is always a balance between needing to buy it or continuing their free version."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
