Hi, We have recently upgraded to grizzly and we have started seeing huge spikes on our network queue.
Our network queue sits on about 1 message per second usually but we get spikes of 200m/s every so often. These spikes are all due to the message get_instance_nw_info. We're pretty sure this is due to a user action and not some periodic task. One thought is maybe something to do with security groups and source groups. We have some tenants with 100+ instances all sharing the same security group source group. We're using nova-network in FlatDHCP mode. Has anyone else seen this? Cheers, Sam _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
