SI
A suitable choice for unified and efficient infrastructure monitoring across diverse environments providing user-friendly GUI, cost-effectiveness, and versatility
We use it for this specific client, they've deployed multiple instances of it across various locations to facilitate monitoring. To effectively monitor their infrastructure, it seems necessary to implement additional monitoring solutions for all three types of devices they have Nagios Fusion…

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

"It is easier for client installation, and the configurations are doable even for a newcomer in the field."
"Being open source lets us customize it for our monitoring needs, saving us money."
"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."
"It's very easy to manage and monitor it."
"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 most valuable feature of PRTG Network Monitor is its ease of use."
"PRTG Network Monitor's best features are its flexibility, ease of implementation, user-friendliness, and intuitive interfaces."
"It is pretty simple to use, which is always a good thing. It's been very reliable in updating us if any issues crop up."
"The email notifications are helpful, and the dashboards are user-friendly for people with little network monitoring knowledge."
"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."
"The product is simple and easy to implement."
"The solution is very easy to use and the web provides information with ease."
 

Cons

"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."
"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."
"The icons on PRTG's network diagram are hard to find. For example, finding the icons for firewalls and servers is difficult, so we're struggling to create the network topology."
"PRTG Network Monitor could improve the price."
"I wouldn't mind better categories for the sensors. When I go to add a new sensor for a new device, there are some categories in there already, and they can be filtered out, but there's quite a large pool of sensors... When I want to go in and find something quite specific, I have got to scroll down and scroll down to find what I'm actually looking for,"
"PRTG Network Monitor can improve by adding prevention and detection features."
"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."
"I would like to see them take their graphing tools and convert them into a collector so that we can point telemetry to them"
"The technical support could respond a little bit quicker."
"The inventory of the device should be improved."
 

Pricing and Cost Advice

"The pricing is quite reasonable, especially when compared to the broader market."
"Licenses are very expensive, so I would like to see cheaper licensing."
"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."
"All monitoring system is close to the same pricing scheme."
"It is expensive."
"I'm paying something like €1000 per year for the maintenance. I've got unlimited sensors."
"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."
"We've got 1,000 nodes and I believe it's a few hundred quid a month."
"We are satisfied with the price."
