- If you are a core reviewer and about to approve a NeutronLibImpact change, please consider
checking the state of all Stadium subprojects by looking at the
`grafana periodic dashboard <http://grafana.openstack.org/dashboard/db/neutron-lib-failure-rate?panelId=4&fullscreen>`_.
This dashboard shows the status of subprojects' unit tests against neutron and neutron-lib
master branches, and even though it is not exactly validating unit tests against a released
version of neutron-lib it may be enough of an alarm bell to indicate that something might
be wrong because of a patch that recently landed in neutron (assuming that the subprojects
still has direct neutron imports). The check happens daily therefore consider waiting to
approve if you are either aware of another impactful change recently merged that has not
been yet processed or you see failure rates spiking.
