Nagios XI Likes & Dislikes

Like

Nagios XI is a user-friendly, cost-effective monitoring tool that supports a wide range of infrastructure components and enables custom alerts tailored to business needs.

Like

The enterprise version is not too expensive compared to competitors. The user interface is simple, basic and easy to use.

Like

Scalable : From small scale enterprise to large scale enterprise IT infrastructure systems, Nagios XI is best suited. Configurations are customizable. This makes Nagios XI the best. 100s of multiple plug-ins. Fast and speedy alerting system. Interface is easily understandable.

Dislike

While the Nagios XI tool offers a high-level overview for monitoring SQL servers, it lacks in-depth insights specifically for SQL database performance issues. However, it remains a reliable solution for general SQL Server monitoring.

Dislike

The product uses many non-native external plugins to monitor various services. Non-native plugins are sometimes out of date or difficult to find technical documentation for.

Dislike

If there is a network outage from Nagios, that might put our IT infrastructure systems in trouble. Because if a monitoring tool is down, we won't know if there is an issue, if there is any, as there won't be any alert. Other than that, I like everything about Nagios XI.

    Nagios XI : Best and Quickest for monitoring your IT Infrastructure systems.

    5.0
    Feb 3, 2025
    A single Nagios XI tool functions like hundreds of IT employees manually monitoring their IT infrastructure systems in an organization. That too with ease ! Nagios XI not only monitors the systems, but also sends an alert through email, SMS, or any ticketing tool. Without Nagios XI, our IT infrastructure systems would be a chaos.

    This is a very good tool regarding flexibility and the ability to monitor a company's full infrastructure. It is somewhat complex to implement at the beginning, and the user interface is not one of the most modern ones. We have also found a huge community for this product.
