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…

Detects suden changes but significant pricing concerns affect the effectiveness of network traffic troubleshooting
We use PRTG Network Monitor for monitoring traffic on interfaces and the behavior of network traffic. If there are sudden changes in traffic or any configuration issues, we can sort them out using PRTG. It's very helpful for troubleshooting and monitoring traffic utilization on our interfaces…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The tool has the ability to look back within a month's data. It is very easy to navigate within the tool and troubleshoot the problem, compared to other solutions that we've used in the past."
"It is very rock solid. We hardly have any hardware issues."
"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."
"When we have mobile operators who are signal partners, where one is the roaming host and another is the roamer, we are able to see their traffic. Their packets are able to detect if any faults to develop, and at what point they fail."
"It's an easy product to set up."
"It has cut our troubleshooting down by days. Once we have a product in place, we show people examples of how it can streamline their troubleshooting 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."
"The most valuable features are speed and cost."
"Accessibility, ease of use (Web GUI, MobileApps). In general, compared with other software"
"PRTG Network Monitor is a very stable product."
"Ability to create a dashboard inside software monitoring."
"The sensors and remote probes are phenomenal. We use them for all of our global sites. The problem with our global sites are that they are all VPNs. If the link goes down, you can't monitor other solutions, as it just goes off the grid. Having remote probes allows them to still carry on and get the information that we need when it comes back up, sending the information to us."
"Stability-wise, I rate the solution a ten out of ten."
"PRTG has improved our visibility and response time to issues related to remote sites."
"We can see trends for a lot of different things, such as hard drive space and bandwidth usage. We can see and plan for the future by knowing, "We're sort of at 75% capacity now. In three months time, we know we're going to be up to 90%,so we need to plan ahead for it, getting upgrades booked in place." Since things like this take time and effort, it's handy to see trends into the future of where our company is going."
"The feature whereby it shows when my hard drives are moving towards thresholds that would be considered outages, before they reach that point - that is valuable."
 

Cons

"Being able to manage the packet flow switches in nGeniusONE would be great."
"We don't use the single pane of glass view, even though we own it."
"The NetFlow Collectors could handle more flows per minute."
"The single pane of glass feed still needs work."
"I'd like them to make the product more user-friendly."
"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. There are a lot of patches for this particular environment, so you have to keep on them. If you lose track of them, then the product is not useful anymore."
"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."
"I would like to see network mapping."
"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"
"The database needs improvement."
"I know we're going to move to Docker applications and I understand that PRTG does some monitoring regarding this. I do not know if it is complete. If it's not yet complete, it's something they should consider improving."
"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."
"Scalability is the only major sticking point for me. There is a recommended number of sensors, which is around 10,000 and we're double that... The only option we have to scale is to buy another core, which would be a separate, stand-alone instance..."
"PRTG Network Monitor can improve Layer 2 and Layer 3 network maps and the GUI more user-friendly. Additionally, they should bundle the features so I can monitor everything on one particular device."
"The clustering aspect needs improvement, as there is a bit of confusion about you do when hit that 5000 probe mark."
 

Pricing and Cost Advice

"I would like it to be more scalable with less spend."
"This product could be cheaper."
"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."
"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
"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."
"The price is a little high."
"We are licensed for 2500 endpoints."
"The pricing is comparable."
"Sensors on free version can run out quick."
"Because we are only on the free version, we have a limited number of sensors. Therefore, we are not monitoring as much as we want to be to obtain historical information."
"PRTG Network Monitor is very expensive."
"When you buy PRTG, everything comes in one bundle. Licensing is very easy."
"There is a license to use PRTG Network Monitor and it is annually."
"We bought a license for 4000 sensors."
