I think we could develop tools and visualizations that would help the debugging tasks. We could make those tasks more visible, and therefore more appealing to the brave souls that step up to tackle them. Sean and Joe did a ton of work improving the raw data, deriving graphs from it, highlighting log syntax or adding helpful Apache footers. But those days they spend so much time fixing the issues themselves, they can't continue on improving those tools. And that's part of where the gate burnout comes from: spending so much time on the issues themselves that you can no longer work on preventing them from happening, or making the job of handling the issues easier, or documenting/mentoring other people so that they can do it in your place. -- Thierry Carrez (ttx) _______________________________________________ OpenStack-dev mailing list OpenStackemail@example.com http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
