Easy to use, and it's possible to customize the product as per the needs we may have but average multi-tenancy aspect
It's supported by the community. We use Icinga, which is not part of the Open-Source platform but is wrapped into a commercial solution from another provider, a local provider in Italy. Icinga is an open-source platform, so it is supported by the community. It's quite easy to use, and it's possible to customize the product as per the needs we may have. So it's not expensive, and it's quite a general purpose. We can easily monitor any kind of infrastructure we encounter. The ability to customize scripts and build your own queries to request information from the infrastructure elements you want to monitor. This level of personalization and customization is highly appreciated. The alerting is the same as any other monitoring platform. It's not a "wow" feature that has changed our lives, but it's perfectly adequate.

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

"Icinga does the job and is fairly stable."
"People should know that it is simple and advanced."
"Icinga has multiple automation and integration features. There is an API for everything and a web UI for configurations. The APIs enable you to automate tasks in Icinga. We can also use plugins to talk to the API. The Icinga Director talks to a database in the background, and you can import settings from the CMDB to all systems in Icinga."
"We monitor all, starting from UPS to international mail chains."
"Macros and the ability to connect it to Google Maps are valuable features."
"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"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."
"This solution has a self-healing handler where if the service is down, it is automatically restarted."
"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."
 

Cons

"The installation and configuration are very complex."
"It is not really adequate for our current needs. It causes additional issues which we have to work around and takes us time that a better solution would not."
"In general, the product does not look good. However, it does what it is supposed to do. So, the improvements should focus on usability and UI."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"We have found some problems with Nagios, and support isn't very responsive."
"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."
"One thing that Icinga lacks is the capability to create advanced and customized dashboards within the tool itself."
"Network Discovery capabilities would be extremely helpful."
"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
"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."
"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're using the free version of Icinga."
"It is cost-effective, and the return on investment can be very interesting because the price is low."
"It's an open-source solution."
"This is an open-source solution with paid support."
"The solution is cheap."
"The product is inexpensive compared to other DBM products."
"Even though Icinga's financial cost is low, it is an expensive product regarding the resources required to maintain and operate it."
"The solution is free to use."
"The pricing is quite reasonable, especially when compared to the broader market."
