Systemspezialist Monitoring Tools Enterprise (\> 1000 emp.) 11/3/2021 "Icinga2 - a very good solution for Monitoring in large environments" 5/5 What do you like best about Icinga Infrastructure Monitoring? Icinga2 is open-source, so the costs are manageable, and the product itself is permanent in development. If something's going wrong or there are failures, it's no problem to reach the developers. It's very reliable; we are a huge company (Gouvernement) and need reliable solutions. With two icinga2 hosts, we can manage over 44000 Services and 3500 Hosts. It uses the same checks as Nagios; if a service-check isn't available, it's easy to write one. Our admins could write checks, too. They use bash, PowerShell, Perl.. or whatever for scripting; it doesn't matter. With the windows agent, we can use PowerShell checks, with Linux agents bash or similarly. Review collected by and hosted on G2.com. What do you dislike about Icinga Infrastructure Monitoring? It's not very much I dislike. Sometimes i feel we could have better modules for icingaweb2, but it's not the blame of the Icinga-developers. Sometimes we have to sponsor when we need functionalities, but it's opensource! Review collected by and hosted on G2.com. What problems is Icinga Infrastructure Monitoring solving and how is that benefiting you? With other solutions, we've had those problems: - we haven't enough licenses for the number of hosts, Icinga doesn't need Licenses, but you could make a contract for support with Icinga partners. - we have had many stability problems with other products, no problem with icinga2 - we had to pay very much for extensions (for example, MySQL monitoring) with other solutions in the past. Now we write it or use monitoring plugins from Icinga, consol-labs,...and so on. With Icinga we are working with our admins; we can monitor what they want. Review collected by and hosted on G2.com.

Security Officer Small-Business (50 or fewer emp.) 3/16/2018 "The most complete open-source monitoring system" 4.5/5 What do you like best about Icinga Infrastructure Monitoring? It is open source and free, meaning the software is easily extendible. All Nagios plugins, as well as all the community plugins are usable with Icinga. You can use alot of advanced features, including check scheduling, notification escalation or a very detailed user access and management system. It is very easy to extend the system with extra checks or hosts due to the templating system. Review collected by and hosted on G2.com. What do you dislike about Icinga Infrastructure Monitoring? The setup of the software can be quite complicated depending on the OS you are deploying on (I deployed on Alpine Linux) and the documentation for this is not complete. After setup, the initial learning curve is quite steep and takes quite some time. For instance, you need to create a notification template to create a notification object to create a user template to create a user, etc. Review collected by and hosted on G2.com. Recommendations to others considering Icinga Infrastructure Monitoring: Do a small pilot before trying to add too much at once. Also consider adding meta-tags to objects, so you can use these to define conditionals. Review collected by and hosted on G2.com.

Review collected by and hosted on G2.com. What problems is Icinga Infrastructure Monitoring solving and how is that benefiting you?

Information Security Specialist Enterprise (\> 1000 emp.) 10/29/2019 "Icinga is great, icinga2 is better." 5/5 What do you like best about Icinga Infrastructure Monitoring? I've worked with Icinga in multiple organizations, spanning thousands of devices. I love the configurability of the Icinga framework, although for admins new to the platform it may seem intimidating to edit the config files. Icinga2 brings additional features that help automate and configure with less flat file configuration needed but neither product should be brought in lightly. They both require a lot of work up front to be tuned in such a way as to provide benefit that can be mapped back to business requirements. Fortunately, there is a plethora of documentation available as they are widely used. Review collected by and hosted on G2.com. What do you dislike about Icinga Infrastructure Monitoring?
