<p class="MsoNormal">Hi Paul,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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></p>

<p class="MsoNormal" style="margin-left:36.0pt">Hi Vitrage developers, <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt">I have a question about vitrage innerworkings, I ported doctor datasource from master branch to an earlier version of vitrage (1.3.1).<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt">I noticed some behavior I am wondering if it's ok or it is bug of some sort.
<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt">Here it is:<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt">1. I am sending some event for rasing an alarm to doctor datasource of vitrage.<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt">2. I am receiving the event hence the alarm is displayed on vitrage dashboard attached to the affected resource (as expected)<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt">3. If I have configured snapshot_interval=10 in /etc/vitrage/vitrage.conf The alarm disapears after a while<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt">fragment from /etc/vitrage/vitrage.conf<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt">***************<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt">[datasources]<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt">types = nova.host,nova.instance,nova.zone,cinder.volume,neutron.network,neutron.port,doctor<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt">snapshots_interval=10<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt">***************<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt">On the other hand if I comment it out the alarm persists
<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt">**************<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt">[datasources]<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt">types = nova.host,nova.instance,nova.zone,cinder.volume,neutron.network,neutron.port,doctor<o:p></o:p></p>

<p class="MsoNormal" style="margin-left:36.0pt">**************<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt">I am interested if this behavior is correct or is this a bug.
<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt">My intention is to create some sort of hybrid datasource starting from the doctor one, that receives events for raising alarms like compute.host.down
<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt">but uses polling to clear them.<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt">Best Regards,<o:p></o:p></p>
