Comment 13 for bug 1783405

Fwiw, in the future you can use subunit2sql with something like:

to get the average test times over the last 300 runs of tempest-full in one go. But, you'll still have to use openstack-health like mriedem did there to get the graphs of the execution time over time for an individual test.
