Claudio Kuenzler - PeerSpot reviewer
A free and time-saving product that helps to monitor servers and network devices
I use the product for server and network device monitoring. A team of five people is managing the solution, and around 50 people are using the solution in the organization Pro-active monitoring and alerting helped us to decrease downtimes of services. The apply rules feature saves a lot of time.…
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

"Icinga does the job and is fairly stable."
"The apply rules feature saves a lot of time."
"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."
"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"The drafts are easy but what I like about Icinga is that there are many add-ons that you can download."
"An affordable solution for small organizations to do basic network monitoring."
"Macros and the ability to connect it to Google Maps are valuable features."
"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."
"It is easier for client installation, and the configurations are doable even for a newcomer in the field."
"It's very easy to manage and monitor it."
"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

"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."
"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."
"The user interface should be improved."
"One thing that Icinga lacks is the capability to create advanced and customized dashboards within the tool itself."
"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."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"The solution lacks many features important to higher-level IT management and network support."
"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."
"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."
 

Pricing and Cost Advice

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