I believe the important point here is to identify additional metrics required and the relevant attributes which can be specified and have them returned to the Collector. Then in turn the collector can either push/pull those metrics/etc into an Anlytics Engine and tools. Its not a good idea to start designing and building analytics engines etc into Ceilometer, it should just the monitor and collecting project.

For the metrics Ceilometer is definitely the place to set and collect what metrics you need to know of for both the Hardware functions (cpu/mem/disk-i/o/nic utilisation etc etc) and also for some base application sets for example on an Apache server the number of TCP-sessions in utilisation etc etc.

I think we can extend Ceilometer API to help build such tools, but I don't think we should build these tools inside Ceilometer.

Yeah, I think that Ceilometer's the place to collect anything. I don't know if that metrics you are talking about are collectable through Nova though.
