It would be a crime to claim to be a person who is interested in Open source monitoring systems, and then not talk about Zenoss. So, even though I had started the deep dive into CRMs, I thought It is my duty to come back and give it the proper respect that it deserves.
Monitoring tools have been there for a long long time. In that time they have built a large user base. The longer the users have been using the product, the tougher it is to break into the already existing market. This is where the difference between Proprietary and Open Source software come into play. The best thing about Open Source is the feel that it makes you feel…”Hell yea, I am contributing to a worthy cause. This, from now on is MY cause!!”
