Description of problem: When alarm's property is updated with the same value than empty record is added to the alarm-history output. Detailed log in the upstream bug Version-Release number of selected component (if applicable): 2015.1.0-2.el7ost.noarch
Yurii we'd like to fix this for A1 but whether that happens or not depends to some degree on whether the upstream fix is ready on master to then be backported to kilo and then in a position where we can push it into the RPM. So yes, A1 is the goal, but the upstream bug is currently being worked on by a non-red-hatter, so there's ambiguity in the timetable over which we have no control.
Added the backport to upstream kilo gerrit.
