<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">It sounds like a bug. Alarms created by a datasource are not supposed to be deleted later on. It might be a bug that was fixed in Queens [1].<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">I’m not sure which Vitrage version you are actually using. I failed to find a vitrage version 1.3.1. Could it be that you are referring to a version of python-vitrageclient or vitrage-dashboard?
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">In any case, if you are using an older version, I suggest that you try to use the fix that I mentioned [1] and see if it helps.<o:p></o:p></span></p>
