** Attachment added: "nova-compute-pci.log"
   https://bugs.launchpad.net/ubuntu/+source/nova/+bug/1387244/+attachment/4248248/+files/nova-compute-pci.log

** Description changed:

+ Environment: Ubuntu 14.04/OpenStack Juno Release
+ 
  The periodic auditing on compute node becomes very RPC call intensive
  when a large number of instances are running on a cloud; the
  InstancePCIRequests.get_by_instance_uuid call is made on all instances
  running on the hypervisor - when this is multiplied across a large
  number of hypervisors, this impacts back onto the conductor processes as
  they try to service an increasing amount of RPC calls over time.

** Tags added: juno scale-testing

** Also affects: nova
   Importance: Undecided
       Status: New

** Summary changed:

- Large number of InstancePCIRequests.get_by_instance_uuid RPC calls during compute host auditing
+ Increasing number of InstancePCIRequests.get_by_instance_uuid RPC calls during compute host auditing
