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.

Quotes from Members

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

Pros

"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."

"The apply rules feature saves a lot of time."

"This solution has a self-healing handler where if the service is down, it is automatically restarted."

"I would recommend Icinga; it's an open-source solution, it's quite easy and simple to use, and checks can be run with Python code and Shell Script code."

"We have found the solution to be stable."

"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."

"The most valuable feature is one that not many are even aware of, as Icinga has a self-healing event handler where if the service is down, it is automatically restarted, and you can configure the handler to take action after the critical alarm without human interaction."

"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."

More Icinga pros

"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."

"It is easier for client installation, and the configurations are doable even for a newcomer in the field."

Cons

"The connection between Icinga and Icinga Web."

"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 tool currently fails to provide notifications to users."

"Icinga’s automation could be improved."

"The user interface should be improved."

"One of the areas that are frustrating is remote monitoring for more than one machine."

"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."

"One thing that Icinga lacks is the capability to create advanced and customized dashboards within the tool itself."

More Icinga cons

"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."

"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."

Pricing and Cost Advice

"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."

"The solution is free to use."

"It is cost-effective, and the return on investment can be very interesting because the price is low."

"We're using the free version of Icinga."

"Even though Icinga's financial cost is low, it is an expensive product regarding the resources required to maintain and operate it."

"The pricing is quite reasonable, especially when compared to the broader market."
