I haven't had to use support very often, but when I have, it has been effective in helping to accomplish our goals. Since Nagios has been very popular for a long time, there is also a very large user base from which to learn from and help you get your questions answered.

A great tool that has many uses, and best of all, it's free. It works just as good as many multi-thousand dollar tools and is easy to set up and configure. For small to medium businesses who want to get on board with a monitoring solution for free, I would highly recommend it. There are some use cases where some other tools might work better out of the box for larger organizations that may demand more out of their monitoring solution, but in many cases, Nagios is more than adequate. With the large variety of add-ons and ways to customize Nagios, it can also tackle the large scale deployments and other useful features.

Nagios is an open source product, which means most of the support comes from the community. Unless you purchase one of the paid products, such as Nagios XI, you can't really expect to see any level of meaningful or traditional enterprise level support. But there's also a distinct lack of account management for the open source product as well, so there isn't a path inside the company typically for customer support.

I have hardly involved Nagios since platform is stable for support but the one time that I did they were very responsive. I would probably suggest faster introduction of new features. Compared to other companies that have adopted agile methodologies for development, I believe that Nagios still has some room for improvement.
