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…

Efficiently monitor networks across regions with seamless setup and robust feature set
PRTG Network Monitor is easy to set up. Within a few minutes, it is operational. It is an all-in-one monitoring solution without extra costs. For example, we set it up for an insurance company with branches across Africa. We are able to monitor from Lagos without installing anything in the branches, using the agentless feature. We just put in the IP address and the parameter, and we monitor from those ends. Additionally, all the sensors are very useful. Most people are interested in the bandwidth monitoring sensor to see what bandwidth the users are consuming. The pricing is affordable compared to SolarWinds.

Quotes from Members

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

Pros

"I love the single pane of glass view. It makes it easier to not have to navigate everywhere. It allows more simplistic visibility, without having to go from tool to tool to tool, or from window to window to window."
"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 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."
"We use it for monitoring whenever we update a new circuit or site."
"It allows us to get quicker resolutions. We can see exactly what is using up the bandwidth, so we can assist end users."
"The most valuable features are speed and cost."
"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."
"It helps us get to root cause quickly. With utilization and consumption of bandwidth, we can usually see what application is taking as much as they should (or shouldn't), then account for it accordingly."
"Ability to create a dashboard inside software monitoring."
"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."
"PRTG Network Monitor helps us quickly and easily discover a large number of sensors, so we can spend minimal time monitoring customer sites."
"The most valuable features of PRTG Network Monitor are user-friendly, and the graphical interface is good for all the network devices that are mapped in this organization. It's very easy to find reports for any devices that we are looking for."
"The alerting is the most valuable feature. I also like the iPhone app. I get alerts in an email on the iPhone app."
"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."
"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."
"I found PRTG Network Monitor very useful for troubleshooting and monitoring the utilization of either the network or server."
 

Cons

"The technology goes end-of-life on us every year, which is why I am looking forward to vSTREAM. I don't like when devices go end-of-life on us so quickly. If we can get more of an advanced notice of when an end-of-life is brought up, because our certification process within the organization takes a while."
"The monitoring and reporting tool needs improvement. Users want more information, such as the level of detail when doing a packet analysis. They want more detail to be able to isolate down to a specific point."
"There is a timeout feature that we have been asking for awhile."
"I would like to see an improved level of stitching between IPs."
"The single pane of glass feed still needs work."
"We don't use the single pane of glass view, even though we own it."
"Being able to manage the packet flow switches in nGeniusONE would be great."
"It's not able to communicate with our probes."
"In terms of sensors and probes, it would be really cool if PRTG had a purely Azure-based solution. We had to install a probe on one of our cloud servers and then let that probe out from there. It would be really cool if it just monitored Azure without having to install something on the device."
"Improvements in data storage flexibility, such as allowing customers to specify data retention periods, would enhance PRTG."
"The operations dashboard is only available in PRTG's enterprise version, but I wish it could be accessed in the standard licensing. It would also be nice if PRTG had templates for dashboard monitoring, software monitoring, etc. It can help me set up a dashboard because now we don't have a template from PRTG, so we need to create one from scratch."
"The thing that we do struggle with a bit is in the historic data. If I want look over 30 days, because it averages out onto one graph, you can't zoom in and drill down information."
"Performance-wise, PRTG Network Monitor still needs improvement because a large number of SNMPv3 queries reduces tool performance."
"We would like more cloud native sensors for AWS, Azure, Google Cloud, etc. A lot of businesses are moving in that direction, so having something where we can pull performance stats out of these cloud services would be great for us."
"Their penetration within the market could be much better. If their pricing was lower, even though it's reasonable now, it might help them achieve this."
"The desktop app is the one area where it do with some improvement. From a user's perspective, I would like to be able to get more out of the desktop app as opposed to where we are now with it."
 

Pricing and Cost Advice

"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."
"I would like it to be more scalable with less spend."
"This product could be cheaper."
"The price is a little high."
"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."
"We have an unlimited license for this solution."
"PRTG is now available as PRTG Enterprise Monitor, and the price varies depending on the total number of sensors the customer buys"
"The price is pretty comparable."
"We pay nothing for it. Its 100 sensors have allowed us to put a magnifying glass on some systems, providing an extra layer of detail. Therefore, our outgoing is nothing and our incoming is a lot of useful data that we can react to proactively."
"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."
"The pricing for PRTG in our case is reasonable because we have a lot of applications to monitor within PRTG. It is not that expensive."
"The pricing is very low compared to other solutions."
"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."
