What is most valuable?

The most valuable features of this product are the very lightweight code and easy-to-manage plug-ins. Apart from the main Nagios core engine, one can add several APIs and add-ons to make the Nagios engine more stronger without compromising... more»

What is most valuable?

Alerting and proactive monitoring are invaluable. It also allows you to write your own plugin if you have no alternatives and you need to have things under control.

How has it helped my organization?

It sends alerts to the right people which ensures there is no delay in the correct person or team looking into issues. It's helped to reduce downtime in the production environment to almost zero. Due to this, we now spend less time on network... more»

What needs improvement?

The configuration and reporting modules need to be improved. I'd like to have them include a basic install package, and if you don't like the packages included, have the ability to can replace them with different ones from the Nagios plug-in... more»

What is most valuable?

Getting the alerts is the most valuable feature. This way I know when servers are acting up or just plainhosed. It also helps me to know which things need to be recovered and when so I do not have to bother with checking into it immediately.

How has it helped my organization?

Before we implemented Nagios, we did not know which servers were up or down until a customer told us. Now, I can see trends over time and it gives me perspective of what needs to be improved and we are able to work proactively as opposed to... more»

What needs improvement?

Generally, it does what I need it to do, but better error reporting would be great. It's so flexible that I do not use half the capability that it has. Also, Nagios 4 does not work with NConf or Adagios so we haven't upgraded yet.

What is most valuable?

It is stable and fit for purpose. Various plugins are available as per your need in the open source marketplace to use and customize according to the need.

How has it helped my organization?

We use other enterprise products for most monitoring activities. However, Nagios has been the product to go to if we need a cost effective solution that can directly fit our needs. We use it in our business operations center to view... more»

What needs improvement?

Setup is bit complicated due to the large set of libraries it needs, but this may be because it's open source.

What is most valuable?

Extensibility is good as this makes it easy to write checks on your own. Also, it's light as since v4 it isn't resource heavy.

How has it helped my organization?

No IT company would survive without a monitoring system. Nagios helped the companies I've worked with to achieve an acceptable level of monitoring.

What needs improvement?

Nagios was not built with scalability in mind. It does not work in a distributed fashion, and fixing this issue would probably require rewriting a big chunk of its code. There are other solutions, born as a fork of Nagios, that do this but it... more»
