"Icinga, the alternative to Nagios"

5/5

What do you like best about Icinga Infrastructure Monitoring?

The large number of plugins/modules it supports, the number of systems it can integrate for monitoring:

* Networks

* Network components

* Notifications

* Alert levels

* Interfaces

The significant improvements it has over Nagios, and the compatibility with its modules. Review collected by and hosted on G2.com.

What do you dislike about Icinga Infrastructure Monitoring?

Some alarms may have a delay, depending on how large the monitoring system is, and they can give false positives, although in Nagios the same thing happens, it doesn't reach 100% real-time but rather 90% or 95%. The large number of views it offers can sometimes be more of a disadvantage than an advantage, as in some views certain alarms may appear and in others different ones... Review collected by and hosted on G2.com.

Recommendations to others considering Icinga Infrastructure Monitoring:

If you have Nagios, I would migrate to Icinga for several reasons, but the most notable are its complete free availability, the large open source community behind it continuously developing the application, and the great support it has thanks to this community of users and developers. Additionally, the number of modules it has is infinite, allowing you to check a large number of systems, networks, freezer or stove temperatures, etc. Review collected by and hosted on G2.com.

What problems is Icinga Infrastructure Monitoring solving and how is that benefiting you?

We use it to monitor the organization's networks and refrigeration equipment, with high monitoring performance, reaching hundreds of monitored devices. Review collected by and hosted on G2.com.
