Every time I crack open a nova logs in detail, at least 2 new olso incubator log issues have been introduced.
The current ones is clearly someone is over exploding arrays, as we're
getting things like:
2014-06-29 13:36:41.403 19459 DEBUG nova.openstack.common.processutils

/opt/stack/new/nova/nova/openstack/common/processutils.py:160
(yes all those spaces are in there, which now effectively inhibits search).
Also on every wsgi request to Nova API we get something like this:

On *every* request.
oslo code, by definition, is going to be used a lot, inside of tight
loops. Which means extremely verbose. Actually
nova.openstack.common.policy currently represents ~40% of all bytes in
nova-api logs (15 MB uncompressed content during a Tempest run).
Both these are bugs that should be fixed, however, I'd like to figure
out how we come up with more systematic approach to keep the quality of
these things up, especially as an oslo fix is expensive in terms of
labor, as we have to fix in oslo first, then sync to projects. And as
more syncs have caused issues like this an oslo sync is not longer a
fast approve as it used to be.
