The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures.
Growing the solution or migrating to the Enterprise version is easy, and various plans are available -if you have one hundred devices or more-. This is an open-source solution that can be used free of charge (Community edition). Libre Software can be let tasted and tried without compromise, no pressure for buying, and no more worries (we have too many of them). Both case use same core, Enterprise version include additional plug-in's and there is total support for specialized cases.
In terms of money, the Enterprise version is the cheapest that I have found after a market study. The best ratio of quality and price, I want to think.
We use the Open Source edition, but I've worked with the Enterprise edition in the past. My rule of thumb would be that if you need more than thirty agents, and you lack an automation tool such as Chef or Puppet, you will save a lot of time and money going to the Enterprise edition.
It is a personal issue, everyone has different needs.
The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest.
The license part is not as complicated as some other solutions. You get the license and it includes updates, new versions, and access to the complete library of modules.
Pandora FMS is easy to implement and the pricing of licenses is competitive.
This product is more expensive.
The license part is the best. Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS. I love the simplicity of the license. This makes it easy to work, with no fear of being asked for more money all the time.
