Harrison Bulley - PeerSpot reviewer
Senior Infrastructure Engineer at Net Consulting
A stable, scalable and cost-effective solution that helps with inbuilt scripts for easy modification
I think the software is quite good, but we have had problems with getting it to recognize certain areas and amend certain checks, where we needed so we would have to create backend scripts for those checks. Though, being open source, it has the support to create backend scripts, it would be better to have these scripts in-built.

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

"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."
"If you have a small infrastructure or a small number of devices that you want to monitor, then I think it's a good solution."
"We have found the solution to be stable."
"Icinga2 was designed to delegate, distribute and balance tasks between several nodes."
"The best thing about the solution is how it highlights errors, the issues, and what needs my attention. The solution directs me to areas that I should look for first."
"I like the ability to amend and adjust things really easily, which is useful in a case where you could make it auto-discover and then set a template to say all of these applications or servers under this template have an automatic threshold set that you’d set up manually."
"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."

"One thing that Icinga lacks is the capability to create advanced and customized dashboards within the tool itself."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"At this time, the layout of the website is a bit difficult. It should be more user-friendly for changing the background and logos."
"Icinga is a complex solution that's hard to learn. It's a powerful product for monitoring, but new users will have a hard time figuring out what to do."
"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."
