RichMeters

The current Ceilometer meters have the following columns (with no defined indices beyond the primary keys on the denormalized tables)

  *source
  *user_id
  *project_id
  *resource_id
  *message_id
  counter_name
  counter_type
  counter_unit
  counter_volume
  timestamp
  resource_metadata

But for SLA/KPI measurements and effective debugging, we've found the following additional columns to be critical (and fully indexed):

    *cell
    *routing_key
    *state
    *old_state
    *task
    *publisher
    *event
    *service
    *host
    *request_id

Our first order of business would be to add this Meter type to Ceilometer and use it as a basis for backfilling the StackTach functionality.
