There are a lot of projects with 0% classification rates on unit test 
job failures, I at least saw Ironic, Horizon, Cinder and Glance.

Ceilometer UT jobs had a 14% classification rate but I think Anita and I 
have most of those fingerprinted now.

This is hoping that people from those other projects and step up and 
help classify their racy unit test bugs, or at least open bugs so we can 
find logstash queries and get elastic-recheck patches up for them.

If you have questions on writing e-r patches, ping me in #openstack-qa.
