** 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
