I prefer very much its scalability. It can handle large-scale infrastructures with thousands or even tens of thousands of hosts without any performance degradation. This makes it an ideal choice for businesses with complex environments or those that are rapidly expanding. Review collected by and hosted on G2.com.

One disadvantage of Icinga Infrastructure Monitoring is that it has a steeper learning curve compared to some other monitoring tools. This may be due to its wide range of features and flexibility which can make it difficult for beginners who are new to infrastructure monitoring. Review collected by and hosted on G2.com.

Ability to integrate the various custom metrics & reporting tool which supports multiple monitoring aspects. I have used Memory, CPU, and Disk IO metrics to be shown in Icinga. Review collected by and hosted on G2.com.

Alerting system is something that I couldn't find in the version I have used, perhaps Alerting could be a great add-on capability such as Mail notifications & PagerDuty alerts etc. Review collected by and hosted on G2.com.

Icinga is free to use, no costs and limts Review collected by and hosted on G2.com.

Complicate Setup because of many combined products Review collected by and hosted on G2.com.

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.

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.

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.

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.

As a free, accessible, and full open sourcing project, Icinga Monitoring offers many organizational monitoring solutions, particularly for hosts and simple analytics alerting, as well as reliable codebase to the decentralized control. I feel like Icinga Monitoring is simpler than other software and it has the most simple securities functionalities you need. Also, It has some good features to use Active Directory or LDAP for accesses. Review collected by and hosted on G2.com.

The learning process is quite high, as with any complex software package. The culture of Icinga Monitoring is good, but it is very difficult to find specific answers for many of the concerns quicker. Review collected by and hosted on G2.com.

One of the best advantage is we have only one ticket instead of more in case of the devices are related to each other during the outage. Easy to navigate on the GUI. It is really easy to setup from the very beginning and easy to make the configuration. We can connect it with lots of 3rd party tools. It is easy to integrate and very simple the structure of the Icinga. It has very good and transparent documentation, if we get stuck with something, easy to look into on the Internet. Review collected by and hosted on G2.com.

It would be really good if we get more function for the basic system. There are lots of useful function is not build in, so we need to add them with plugin. Review collected by and hosted on G2.com.

Automatic massaging by sms doesn't work well, telegram is better Review collected by and hosted on G2.com.

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.

The flat files can be intimidating, and the web interface plugin is not very intuitive. Easy to script and automate, however. Review collected by and hosted on G2.com.
