Senior Systems Administrator at a tech vendor with 10,001+ employees
Delivers comprehensive and customizable system management with increased efficiency
The best features I have found are that it is very customizable, which would be number one, and very extensible through the use of scripts and triggers. The visual look of the interface is very easy to understand what is happening and somewhat why it's happening. It may sound facetious, but it really is everything about it. Everything works exactly the way it's meant to, a dream come true for anyone who's administering systems because it gives you all the information that you want and all the actions you want to take, all in one place. The benefits I have seen from using it so far include the ability to know in advance and take actions based on the information the tool gives you.

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…

Quotes from Members

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

Pros

"The script-based actions have allowed us to extend the core reporting capabilities."
"ControlUp has an easy installation process."
"It has a great career time monitoring tool."
"The most valuable feature is the granularity of visibility into the resources that are in use by our applications."
"ControlUp has some good functionalities, such as remotely pushing scripts in the device through the tool."
"ControlUp has a lot of automation in it; it detects problems and failures very well, and it's not only monitoring, but it's also detecting, and it could even fix problems with a lot of automation that you can put in place to fix problems automatically before you even detect them."
"Security, uptime, and reduced capital expenditures are the main reasons we use ControlUp. So basically, the money that we consume is based on the amount of time we are using a service."
"The visual look of the interface is very easy to understand what is happening and somewhat why it's happening."
"Being open source lets us customize it for our monitoring needs, saving us money."
"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."
"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."
 

Cons

"The graphical user interface needs to be improved from version to version."
"There is area for improvement, maybe in the reporting. It could use some work in reporting."
"ControlUp could improve the integration. Microsoft Azure Virtual Desktop monitoring has better integration."
"We'd like to see the mobile app working again so that we can get alerts 24/7. This is especially useful for the person on call."
"It is expensive. It is very expensive. I was working in a bank, and even in the bank, which was quite healthy, the ControlUp budget was something we had to defend very harshly."
"Most reports give information about the top 100 devices, but not all of the devices."
"Integration is always a problem, and we feel that we are doing our best and the service provider thinks they are doing their best. I guess if ControlUp's system could be more capable or if people could understand the integration part, that would be better."
"There was some lag earlier, and reports pulled from the dashboard would sometimes be half an hour old. But now, the information provides real-time status, which is greatly appreciated. Overall, I've seen improvement in the product."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."
"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
"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."
 

Pricing and Cost Advice

"We are satisfied with the price compared to other solutions."
"Based on my experience, ControlUp is not that expensive."
"Personally, I would say that the only thing I could compare it to is another monitoring tool that we use, Nagios."
"The pricing is quite reasonable, especially when compared to the broader market."
