So
we would write "raise alarm" actions in the scenarios of the template. I think that the alarm is reported or is deduced should be a state property of the alarm. The vertex reported and the vertex deduced of the same alarm should be merged to one vertex. </span></span><u class="gmail_msg"></u><u class="gmail_msg"></u></p>

This problem depends on the specific Nagios tests that you configure in your system, as well as on the Vitrage templates that
you use. For example, you can use Nagios/Zabbix to monitor the physical layer, and Vitrage to raise deduced alarms on the virtual and application layers. This way you will never have duplicated alarms. If you want to use Nagios to monitor the other layers
as well, you can simply modify Vitrage templates so they don’t raise the deduced alarms that Nagios may generate, and use the templates to show RCA between different Nagios alarms.</span></span><u class="gmail_msg"></u><u class="gmail_msg"></u></p>

<span class="m_6050535089027343835m_-8650903509567554519gmailmsg gmail_msg"><span style="font-size:11.0pt;font-family:Calibri" class="gmail_msg">Now let’s talk about the more general case. Vitrage can receive alarms from different monitors, including Nagios, Zabbix, collectd and Aodh. If you are using more than one monitor, it
is possible that the same alarm (maybe with a different name) will be raised twice. We need to create a mechanism to identify such cases and create a single alarm with the properties of both monitors. This has not been designed in details yet, so if you have
any suggestion we will be happy to hear them.</span></span><u class="gmail_msg"></u><u class="gmail_msg"></u></p>
