Much less the application layer, physical SW installs or logical groupings layer, or a virtual hosts or internal cloud stack layer. Or tie ins to the release management or DevOps control layer.
I know this is NANOG, but configuration control runs a ways up the stack... A proper CMDB will have to be able to take a much bigger picture.
Not to slight Zenoss; it's good at what it does do. But that's not a CMDB.
That is not to suggest that products that handle a limited slice of the stack in a more organized manner are not valuable. Every little bit helps, in the current absence of a delivered off-the-shelf comprehensive product.
But if you've ever watched a comprehensive product run, partnered with a systems deploy tool with all the business logic on physical anti-affinity for power, rack, network layers, ... Provisioning a 1000+ node, 60+ server types app environment into a data center with one command line, selected, booted, network side VLANs allocated and configured, apps installed, apps configured, and ready for traffic...
The data to be able to pull that off can be gathered and can be managed and used effectively. That's the power of a real, comprehensive CMDB.
