i did notice the collector service was only ever writing one db connection at a time. i've opened a bug for that here: https://bugs.launchpad.net/ceilometer/+bug/1291054 i am curious as to why postgresql passes but not mysql? is postgres actually faster or are it's default configurations set up better? cheers, gordon chung openstack, ibm software standards -------------- next part -------------- An HTML attachment was scrubbed...
