sorry, missed this while we were busy with release. can you clarify what 
data you want? we currently have different agents that gather metrics in 
various ways.

polling agents - periodic querying of various apis
	- compute/ipmi agents - exist on host and query for host and guest 
level metrics
	- central agent - exist usually on controller node and query service apis

notification agents - listens to service queues for any messages published.
