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…

Has reduced troubleshooting time and improved issue detection through sensor alerts and team collaboration
PRTG Network Monitor can be improved because the dashboard themes feel outdated. It should be updated to a newer version for the new Gen Z customers. The notification sound options are limited unless customized. Restarting probes after Windows updates is necessary, and there should be some kind of automatic restart. The initial auto-discovery added too many unnecessary sensors, so auto-discovery should only take the necessary sensors into consideration.

Quotes from Members

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

Pros

"This solution has cut our overall troubleshooting time, sometimes going down to a few hours over what might have taken one to two days to fully troubleshoot an issue, and it has helped to increase our application uptime as we try to keep the five nines."
"Because we are doing proactive monitoring instead of reactive, the end users don't even see that there is something wrong."
"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."
"The ability to troubleshoot customers' connectivity has been very beneficial."
"It is very rock solid, and we hardly have any hardware issues."
"Go with NETSCOUT."
"The real-time troubleshooting and application segregation that you can do within it."
"This solution provides us with the needed feedback on our IT infrastructure. It allows us to grab all the information from a single point of view."
"It has provided us with early warning for potential issues and has stopped potential downtime before it occurs."
"It is able to satisfy all our requirements in terms of email notifications and specific errors on the devices."
"The real-time monitoring feature in PRTG is invaluable to me"
"Stable and scalable network monitoring tool. Installation is simple and straightforward."
"Ability to create a dashboard inside software monitoring."
"One of its valuable features is the fact that it handles multiple operating systems... And I like the fact that it tells me when things are about to fall over, which means I can preempt it and not have to wake up at three in the morning to fix it."
"PRTG Network Monitor is perhaps the most accurate tool we have used to monitor the capacity of the WAN connection."
 

Cons

"We don't use the single pane of glass view, even though we own it."
"The technology goes end-of-life on us every year, which is why I am looking forward to vSTREAM."
"The solution is not great, but it is not bad."
"There is a timeout feature that we have been asking for awhile."
"The monitoring and reporting tool needs improvement."
"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."
"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 scalability has some limitations and quirks to it. I would like to be able to upgrade rather than replace the whole thing."
"The user interface could be more modern as it is quite dated. PRTG Network Monitor can sometimes be too detailed and cluttered at the beginning, making it heavy to use."
"PRTG Network Monitor could improve by having descriptions for the tab usages. The dashboards or interface could be easier to understand."
"PRTG Network Monitor can be improved as there is a lot of manual cleanup needed, which could be reduced."
"If they are looking for complex reports, I will say stay away from this product."
"In the next release, PRTG Network Monitor should add a backup solution."
"PRTG Network Monitor needs to enhance network performance monitoring."
"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."
"Improvements in data storage flexibility, such as allowing customers to specify data retention periods, would enhance PRTG."
 

Pricing and Cost Advice

"I would like it to be more scalable with less spend."
"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."
"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."
"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."
"We pay for a perpetual license and we have a support fee."
"It's a cost-efficient tool."
"There is a license to use PRTG Network Monitor and it is annually."
"We pay for PRTG Network Monitor annually. The price is approximately 10,000 rupees annually."
"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."
"When you buy PRTG, everything comes in one bundle. Licensing is very easy."
"The price of PRTG Network Monitor is reasonable."
"PRTG Network Monitor is very expensive."
