Nagios

Nagios Enterprises offers monitoring and alerting solutions for servers, switches, applications, and services. Put simply, it is about building software for you when nothing off the shelf fits.

The natural audience is companies with a specific process to automate. As a small company team themselves (11 to 50 people), they tend to serve customers of a similar scale best. You will probably talk to the people who build it, which is great until you need 24/7 support.

Nagios is based in Saint Paul, Minnesota and founded in 2007. More on nagios.org.

Things worth asking about: portfolio relevance, who owns the code, and how they handle changes. A short pilot with your real data tells you more than any demo.

Every review on Revaw shows how it was verified, so if you know Nagios well, your review carries weight here.
