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 artificial intelligence and automatic detection system in Flowmon Solution are perfect for every, type of customer, such as government and commerce."
"The solution is stable."
"It is an open platform, so in terms of integration, we are quite happy. We can integrate it with other SNMP solutions. We can also integrate it with security solutions, such as a SIEM solution."
"Flowmon is more easy to understand and helps find network issues more quickly."
"Flowmon is more easy to understand and helps find network issues more quickly."
"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. I can write a customized script for a sensor to detect specific things."
"My opinion is that this solution is not very expensive."
"Ease of set-up – it is quick and easy to add a probe and start collecting data from a device."
"I really love the activity library. It gives the flexibility to discover data and metrics about my interface and data server."
"Every monitoring session features similar capabilities."
"The tool is integrated with our email for the alerts."
"It's very easy to manage when you've got time to do some work on it: things like adding devices, adding groups, adding sensor clusters, and being able to clone and move stuff around."
"The solution has excellent redundant features."
 

Cons

"The licensing price could be better."
"I do not know the detailed pricing."
"It would be helpful to have more details about the monitoring of the infrastructure. It should have support for SNMP. This is something that is currently not there in the product."
"If there was better visualization in Flowmon Solution it would be good."
"PRTG Network Monitor should provide syslog monitoring since it is not available at this time."
"When using PRTG Network Monitor it is beneficial if you have prior experience with it, the user interface could improve."
"The scalability of this solution could improve as well as the automated provisioning of the infrastructure."
"We run it in a cluster, so we have two that run together. The cluster behind it is sketchy at times."
"I would like a more straightforward ability to create dashboards and maps. The network maps should be a bit more flexibility in the GUI to do what we need to do."
"I would like to see network mapping."
"Sometimes, our PRTG Network Monitor system crashes and a lot of sensors go down."
"PRTG does not allow us to scan devices like we can scan software or another problem in it. Also, I cannot draw graphical graphs in Woodview/look. Another problem is that we cannot draw a good diagram in PRTG."
 

Pricing and Cost Advice

"It works with a permanent license, and then you can pay for the support. For the gold support, you need to pay yearly."
"The price of the solution could be better."
"The licensing fee accrues only once, but that of support is annual."
"We are using the basic PRTG that we can download for free. For now, we only need to monitor less than 100 devices. For more than 100 devices, we would need to buy a license. PRTG is much cheaper than SolarWinds."
"On a yearly basis, I believe it's between £1,200 and £1,500."
"We have an unlimited perpetual license, so we just pay support costs and it can scale throughout the organization."
"If you are not too sure about it, try the free version. Then, if you like it, you can go to the paid version and roll it out."
"The price of PRTG Network Monitor is reasonable."
"The scalability is there, but smaller companies might need CAM software to be able afford the product."
"In my company now, we are using the free version."
"We used a product called SolarWinds in the past, and its cost was high. Whereas, PRTG came in at a third of SolarWind's cost."
