Reviewing the system architecture now provides us with an understanding that can help troubleshoot problems that may arise later. However, reading it to start using Zenoss Core is definitely not required. So feel free to come back later.
Zenoss Core builds upon several open-source software projects to create a robust network and systems management solution. The most notable open-source software components that integrate with Zenoss Core include Zope, Python, MySQL, RRDtool, and Twisted.
When we talk about the system architecture, it helps to conceptually segregate Zenoss Core into three layers:
