Featured Reviews

Harrison Bulley - PeerSpot reviewer
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.
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…

Quotes from Members

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

Pros

"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."
"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."
"The drafts are easy but what I like about Icinga is that there are many add-ons that you can download."
"There's a module called Icinga Director, which helps us configure the product using an intuitive interface through clicks instead of creating a text configuration. It's very helpful for us."
"Icinga does the job and is fairly stable."
"An affordable solution for small organizations to do basic network monitoring."
"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."
"This solution has a self-healing handler where if the service is down, it is automatically restarted."
"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."
"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."
"It's very easy to manage and monitor it."
 

Cons

"The solution lacks many features important to higher-level IT management and network support."
"Icinga’s automation could be improved."
"It needs Trap SNMP. I saw the documentation for Zabbix, that it has its own built-in product which handles SNMP traps, and there's nothing similar in Icinga or Nagios. I think this feature is most important for me."
"The user interface should be improved."
"We have found some problems with Nagios, and support isn't very responsive."
"The installation and configuration are very complex."
"At this time, the layout of the website is a bit difficult. It should be more user-friendly for changing the background and logos."
"The tool currently fails to provide notifications to users."
"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."
"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."
"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

"It's an open-source solution."
"It is cost-effective, and the return on investment can be very interesting because the price is low."
"The product is inexpensive compared to other DBM products."
"The solution is free to use."
"The solution is cheap."
"This is an open-source solution with paid support."
"Even though Icinga's financial cost is low, it is an expensive product regarding the resources required to maintain and operate it."
"We're using the free version of Icinga."
"The pricing is quite reasonable, especially when compared to the broader market."
