Re: [openstack-dev] [Ceilometer] time consuming of listing resource
I think the better way is save meters as a field in resource table. You can look at MongoDB model and may get some ideas. Beside above, sql backend can introduce Memcache to improve performance. IMO, the best way may be redesign the sql model to match workload.

So the time of whole process is too long. I think the meter of Resource object can be reduced and I have tested this modification, it is OK for listing resource,and reduce the most time consumption I have noticed that there are many methods of db operation may time consumption. ps: I have configured the ceilometer pulling interval from 600s to 60s in /etc/ceilometer/pipeline.yaml, but the invironment has just run 10 days! I'm a beginner of ceilometer,and want to fix this bug,but I haven't found a suitable way may be someone can help me with this?

Some VMs who wants to access the Host may need like running qemu-guest-agent or any proprietary software want to use this mode of communication with Host. Qemu-GA uses virtio-serial communication. We want to propose a blue-print on this for IceHouse Release. Anybody interested on this. Great! We have common interest and I hope we can promote it for IceHouse. BTW, do you have a initial plan or description about it.

Recently there was a nice change that removed the number of entries which helps with the merges. One thing that I have encountered over the last 2 days is that the pep8 passes with my environment and fails with the gaiting. Would it be possible that Jenkins updates the nova.sample.conf in a similar fashion to the way that is done with the translations? +1, I encountered the same problem and I think the task running gererate_sample.sh should be given to Jenkins Thanks Gary ___ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev Best regards, Haomai Wang, UnitedStack Inc. ___ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev Best regards, Haomai Wang, UnitedStack Inc. ___ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
