[openstack-dev] [taskflow] How to use the logbook

Hi there!

I'll be back next week but the feature u are wanting currently doesn't exist (so that would be why u aren't seeing such data). If u want it then a blueprint or spec seems appropriate for this kind of historical information.

Sound good?

Btw, the logbook is more for state and flow persistence so that's why there currently isn't any job information in there.

A job history though seems very useful for this kind of analysis and a few others that have been brought up. Let's make it happen :)
