** 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 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1387244 Title: Increasing number of InstancePCIRequests.get_by_instance_uuid RPC calls during compute host auditing To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/1387244/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
