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…
Tochukwu Uzomba - PeerSpot reviewer
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

"It's very easy to manage and monitor it."
"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."
"Ability to create a dashboard inside software monitoring."
"The feature I like is that it can easily do a lot of mapping."
"PRTG has improved our visibility and response time to issues related to remote sites."
"The solution provides us response times to issues."
"The tool is integrated with our email for the alerts."
"The most valuable feature of this solution is being able to see things graphically."
"One of the valuable features is the diversity of metrics available to us to monitor. It's all there, it's all in the box. It's all made very easy, by virtue of it being pre-configured."
"PRTG Network Monitor's best features are its flexibility, ease of implementation, user-friendliness, and intuitive interfaces."
 

Cons

"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."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
"They just released a newer version of the desktop app, a beta version, that I have been trialing out. I prefer the older version, only because of how the layout is designed"
"Sometimes, it is difficult to drill down further to get information, e.g., if we saw spike in traffic, then we would want to drill down and find out what is causing that spike in traffic."
"The solution has to evolve as an end-to-end monitoring solution. It has to do better at understanding the application at the deepest level."
"We're using more cloud services now. It would be useful to be able to get information back from these cloud services in detail, and display any issues within PRTG for the rest of our systems."
"I would like the ability to monitor Cisco IRS devices."
"The technical support from PRTG needs significant improvement."
"Technical support is an area with concerns in PRTG Network Monitor, where improvements are required."
"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."
 

Pricing and Cost Advice

"The pricing is quite reasonable, especially when compared to the broader market."
"The price was pretty good, very competitive."
"The pricing is comparable."
"One thing I like is that when you buy sensors, it's a perpetual license, so once you buy 2,000 sensors, you've got 2,000 sensors; it's not a recurring cost."
"We are licensed for 2500 endpoints."
"Sensors on free version can run out quick."
"Our licensing costs are 10,000 euros over three years."
"We have unlimited devices and sensors, and it is a bit pricey, but we do have unlimited sensors. With all things considered the price is fine, related to the solution itself. PRTG Network Monitor is good value for money."
"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."
