<p class="MsoNormal">Hi Vitrage developers, <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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">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">Here it is:<o:p></o:p></p>
<p class="MsoNormal">1. I am sending some event for rasing an alarm to doctor datasource of vitrage.<o:p></o:p></p>
<p class="MsoNormal">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">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">fragment from /etc/vitrage/vitrage.conf<o:p></o:p></p>
<p class="MsoNormal">***************<o:p></o:p></p>
<p class="MsoNormal">[datasources]<o:p></o:p></p>
<p class="MsoNormal">types = nova.host,nova.instance,nova.zone,cinder.volume,neutron.network,neutron.port,doctor<o:p></o:p></p>
<p class="MsoNormal">snapshots_interval=10<o:p></o:p></p>
<p class="MsoNormal">***************<o:p></o:p></p>
<p class="MsoNormal">On the other hand if I comment it out the alarm persists <o:p>
</o:p></p>
<p class="MsoNormal">**************<o:p></o:p></p>
<p class="MsoNormal">[datasources]<o:p></o:p></p>
<p class="MsoNormal">types = nova.host,nova.instance,nova.zone,cinder.volume,neutron.network,neutron.port,doctor<o:p></o:p></p>
<p class="MsoNormal">#snapshots_interval=10<o:p></o:p></p>
<p class="MsoNormal">**************<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am interested if this behavior is correct or is this a bug.
<o:p></o:p></p>
<p class="MsoNormal">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">but uses polling to clear them.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Best Regards,<o:p></o:p></p>
