Quick identification of network issues enhances performance monitoring
We will try to Proof of Concept (POC) to a client in Taiwan. We just use the features for the Network Performance Monitor (NPM) Flowmon is more easy to understand and helps find network issues more quickly. We need this solution to monitor the network performance. We started using it three…

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 solution is stable."
"The artificial intelligence and automatic detection system in Flowmon Solution are perfect for every, type of customer, such as government and commerce."
"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."
"The authentication links into our standard Active Directory authentication, which is very good."
"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."
"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."
"The reporting module is easy to configure."
"The most valuable feature of PRTG Network Monitor is its ease of use."
"It helps the entire organization become digitally enabled."
"Ease of set-up – it is quick and easy to add a probe and start collecting data from a device."
"Stability-wise, I rate the solution a ten out of ten."
 

Cons

"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."
"The licensing price could be better."
"If there was better visualization in Flowmon Solution it would be good."
"I do not know the detailed pricing."
"The remote probes seem to be a little bit buggy at times. They just stop working or they say they can't communicate. What we tend to do to is install the remote app onto the servers that we use. That seems to clear it up."
"There seems to be a big jump from the basic scan to the really thorough scan. There is a big jump in the quantity of sensors it uses for certain things. One minute you might get ten and then the next you get 200. There seems to be a big jump between the two at times."
"A room for improvement in PRTG Network Monitor is its sensors. Its application technology sensor, such as the IAS, .NET, etc., needs some improvement because it doesn't work as expected. For example, the IAS sensor doesn't give immediate information, and the information you get from it isn't of good value. The web GUI of PRTG Network Monitor also needs improvement because errors keep popping up if it's not been updated to the latest version. What I'd like to see in the next release of the tool is end-to-end topology mapping for the business model, and that should be required. There has to be a technical map. Technical mapping and topological creation are missing in PRTG Network Monitor, so I would like to see those in the future."
"PRTG Network Monitor should provide syslog monitoring since it is not available at this time."
"Needs ability to monitor standard notification time (notify after X time)."
"There is room for improvement in this solution for the performance and third-party monitoring protocols. They need to be updated to the latest ones."
"The solution could be better and faster when it comes to performance."
"PRTG Network Monitor is okay to use, but you'll need some time to analyze the data. If it can automatically locate or identify the problem area, it would be more helpful to users."
 

Pricing and Cost Advice

"The licensing fee accrues only once, but that of support is annual."
"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 price of PRTG is reasonable. PRTG's competitors like SolarWinds and ManageEngine charge more for the same functionality."
"The price is actually on the cheaper side. If you're going with the unlimited license code, it's very cheap compared to competitors unless you're going for something free, like Zabbix. But you get what you pay for, and it doesn't have the full suite of products or tools like SolarWinds or a ScienceLogic."
"Our licensing costs are 10,000 euros over three years."
"At the moment I'm only using 500 sensors. I pay yearly, so it's a cost that's easily swallowed."
"The ability to use the base version with 100 free sensors is great. The cost on other packages can be very reasonable."
"We pay for a perpetual license and we have a support fee."
"I'm paying something like €1000 per year for the maintenance. I've got unlimited sensors."
"When you buy PRTG, everything comes in one bundle. Licensing is very easy."
